Nothing, is the short answer. Fix four things that cost nothing, in that order, and then decide about a machine in six weeks for a completely different reason than the one you are asking about today. The word in your question that tells me most is “morning”. A clinic that smells of disinfectant all day has a dosing problem. A clinic that smells of it specifically in the morning has an hour problem, and an hour problem is the cheapest thing in this subject to correct because it is a line at a handover rather than a purchase. The four are the mopping hour, the measured dilution, how often the mop head is changed, and one window. If I sold you a diffuser today it would sit on top of a wet floor and your patients would notice two smells instead of one, which is worse than what you have now and would cost you ₹11,999 for the privilege. So let me take this the way I would take it on the phone, starting with the questions I would ask you.
Quick answers — read this first
The four free corrections, in order: move the public-area wash out of the half-hour before opening and into the quiet gap between your two peaks, or do it the night before with a dry buff at T-45 · measure the concentrate in millilitres against the printed dilution instead of pouring capfuls · launder every mop head nightly, dry it flat and open, one head per zone per day · open one window or confirm one extract fan is running for the first forty minutes of the day.Small purchases, if you want them: a marked measuring jug and a laminated millilitre card about ₹250 · twenty-four flat microfibre mop heads about ₹1,800 for the year · a drying rack for the cleaning store from about ₹900.
What to tell patients who mention it: that you have changed when the floors are washed, and that you would rather the place smelled of nothing than of something added on top. The sentence for the front desk.
The machine, if at all: in six weeks, once the building smells of nothing in particular, as a presentation choice. The Vaayu at ₹11,999, public areas only, on low. Housekeeping, not treatment.
The short answer
Short answer: fix four free things before you buy anything. One, move the public-area floor wash out of the half-hour before opening, because that is what puts your first forty patients into the drying phase. Two, measure the concentrate in millilitres against the figure printed on the drum, because pouring by capful typically lands at two to five times the label and the surplus is residue that keeps releasing. Three, launder and dry every mop head flat overnight and run one head per zone, because a soured head distributes yesterday's chemical across today's lobby. Four, give the building forty minutes of air at the start of the day. All four are free, and together they are almost always the whole complaint.
The order, and why: the hour first, because your question says “every morning” and that narrows it to one decision made at one time of day by one person. Then the dilution, because it is the thing that makes the hour matter. Then the mop head, because it is the only one of the four where the smell is no longer coming out of the drum. Then air, which is what clears what is left. The machine is not fifth on this list; it is a separate decision taken later, and in roughly a third of the clinics I talk to it never gets taken at all.
If you do buy, later and for a different reason: the Vaayu at Rs 11,999 — waterless cold-air nebulisation with no standing water tank, up to 1000 m³, a 400ml fill lasting about seventy-five days, app control with 1h/4h/8h/24h timers, under 38 dB, auto-stop and a key-lock for a public waiting area. The Aangan at Rs 25,999 for a large centre or an atrium. An alcohol-free reed diffuser from Rs 749 for an administrative cabin. Free shipping above Rs 499. Buying it to cover a wet floor is the one use I would argue you out of.

Straight answer
Our polyclinic smells of disinfectant every morning and patients have mentioned it — what should we fix before we buy anything?
1. The hour, and it is free. Ask one question at the morning handover: what time are the lobby, the waiting area and the corridors washed. In most Indian polyclinics the answer is somewhere between half past eight and five to nine, because presenting a freshly washed floor before the first patient feels like doing the job properly. The effect is that your first forty patients arrive during the drying phase. Move the public-area wash to the quiet gap between your two daily peaks, which in most polyclinics is between half past two and half past three, or wash the night before and give the floor nothing but a dry buff forty-five minutes before you open. Clinical floors, sanitary areas and the sluice keep their own product and their own frequency and are not part of this.
2. The dilution, measured, and it is also free. Read the figure printed on the drum — Indian floor concentrates are usually specified between one in forty and one in a hundred — and then watch what actually goes into the bucket. If it is poured by capful into a bucket nobody has measured, you are routinely at two to five times the label. The extra concentrate does no extra work: the product has a contact time it already meets at its stated dilution, and the surplus is residue that goes on releasing for hours after the floor looks dry. A marked jug and a laminated millilitre card above the sink is about ₹250 and the correction itself is free.
3. The mop head, and how often it is changed. A head that finishes the evening round standing in a bucket of dirty solution inside a closed cupboard has eleven warm hours to go sour, and in the morning it is walked across your lobby and two hundred feet of corridor. No dilution change fixes that, because the smell is not coming out of the drum any more. Laundered nightly, wrung properly, dried flat and open on a rack, one head per zone per day so nothing runs for twelve hours and the lobby never shares a head with a dressing room.
4. One window, or one extract fan, for the first forty minutes. Whatever is in the building at eight is what greets the first patient at nine. Open the one openable window in the corridor, hold a tissue to every toilet extract grille to confirm the fans are actually running, confirm the fresh-air damper on the air-conditioning has not been shut by somebody chasing a cooling bill, and set the indoor units to fan-only for the last ten minutes of the previous evening so the coils dried before the building was locked. That is four minutes of work for a whole floor and it costs nothing.
5. Then wait six weeks, and say something to the patients who mentioned it. A building takes a few days to clear even after the source stops, and a complaint takes longer than that to stop being repeated. Tell the people who raised it what you changed. What to say at the desk is a short script and having the sentence written down matters more than it sounds.
6. And then, if you still want a machine, buy it for a different reason. Not to cover the disinfectant, which it will not do, but because a polyclinic that now smells of nothing in particular can hold one low, unremarkable background through its opening hours and read as somewhere looked after. That is presentation and housekeeping. The Vaayu is ₹11,999. It makes no clinical claim, it does not purify or disinfect anything, and the clinical rooms stay fragrance-free.

TL;DR: move the wash out of the half-hour before opening, measure the concentrate in millilitres, launder and dry the mop heads flat overnight with one head per zone, and give the building forty minutes of air at the start of the day. All four are free. Wait six weeks. Then buy a machine only if you still want one, and not to cover a wet floor.
Four free corrections, then a decision you can take calmly
SOSA commercial scenting from ₹899
The word in the question that matters is “morning”. An all-day smell is a dose. A morning smell is an hour, and an hour is free to move. Then the measured dilution, then the mop head, then one window — four corrections, no quotation, no purchase order. Fragrance is a separate decision taken six weeks later: the Vaayu at ₹11,999, the Aangan at ₹25,999 for a large integrated centre, and an alcohol-free reed diffuser from ₹749 for an administrative cabin. Free shipping above ₹499.
The four free corrections, in the order I would make them
I want to be clear about why this page spends most of its length on housekeeping rather than on what I sell, because it is not modesty. A fragrance released into a room that has a wet phenolic floor in it does not replace that smell. It sits on top of it, and the pair is more noticeable than the single smell was, which means the ₹11,999 would make your actual complaint worse while appearing to be a solution. That is the whole of my objection and it is a technical one rather than an ethical pose. The second reason is that the complaint you have described is specific to one time of day, and a problem with a time of day is almost always a problem with a decision somebody takes at that time of day. There are only four such decisions in a polyclinic morning and all four of them belong to housekeeping. None of them needs finance, a quotation, or permission from anybody above your housekeeping supervisor, and the one with the biggest effect can be made at tomorrow's handover in a single sentence. The all-day version of this page goes further into the chemistry; this one stays on the morning.
1
CORRECTIONS ONE AND TWO
The mopping hour, and the dilution measured in millilitres
Correction one is the hour, and in a clinic whose complaint is specifically about the morning it is usually the entire answer. Find out exactly what time the public floor is washed, from the person who washes it, not from the schedule on the wall. The default across Indian polyclinics is the half-hour before opening, and the instinct behind it is a good one: nobody wants the first patient of the day to walk onto yesterday's floor. The problem is arithmetic rather than intent. A mopped hard floor releases most strongly while it is drying, which is roughly the twenty to forty minutes after the mop passes, and if the mop passes at twenty to nine then the release peaks exactly as your queue forms. Move it. The quiet gap between your two peaks is usually between half past two and half past three in a polyclinic, and a floor washed then dries into an empty room. If your layout makes an afternoon wash impossible, do it the night before and give the floor nothing but a dry microfibre buff at forty-five minutes before opening, which lifts overnight dust without wetting anything. The clinical floors, the sluice and the sanitary areas keep their own frequency and their own product and nothing on this page touches them. Correction two is the dilution, and it is what makes the hour matter so much. The drum has a figure printed on it. Somebody is pouring capfuls into a bucket whose volume has never been measured, which lands at two to five times that figure in every clinic I have checked, and the surplus concentrate does not clean better — the product meets its contact time and its surface specification at its stated dilution, and anything beyond that is residue sitting on your floor releasing for hours. A marked measuring jug tied to the trolley and the millilitre figure laminated above the sink costs about ₹250 and turns a guess into a measurement. The correction itself is free; the ₹250 is what keeps it correct after the supervisor who understood it moves on.
2
CORRECTIONS THREE AND FOUR
Mop-head turnover, and one window for the first forty minutes
Correction three is how often the mop head is changed, and it is the most overlooked object in clinic housekeeping. I ask to see the cleaning store on every visit and the answer is usually in there: one or two heads standing in a bucket of grey solution, behind a closed door, in a room with no air in it, since about seven the previous evening. Eleven warm hours is more than enough for that to turn, and what happens next is that it is wrung out and walked across the lobby, the waiting area and two hundred feet of inter-departmental corridor before your first patient arrives. That is a morning smell with a very specific cause and it will survive any amount of correct dilution, because the source is no longer the drum. The routine: laundered every night, wrung properly, dried flat and open on a rack rather than hung in a bucket or shut in a cupboard. Twenty-four flat microfibre heads at roughly ₹1,800 for the year gives you one head per zone per day, so nothing runs for twelve hours and the lobby never shares a head with a dressing room or a sluice. The store itself needs air: an extract grille, a louvred door, or simply a door propped ajar overnight, which costs nothing and is the cheapest line on this page after the hour. Correction four is air, and in the morning it is the one correction that works on whatever is left. Whatever is in the building at eight o'clock is what greets the first patient at nine, and most polyclinics spend the night sealed. Four things, none of which costs anything: open the one openable window in the corridor or stairwell for the first forty minutes; hold a tissue to every toilet extract grille and confirm the fan is actually running, which takes four minutes for a whole floor and fails more often than anyone expects; confirm the fresh-air damper on the air-conditioning is open, because in a surprising number of buildings somebody shut it to save on cooling; and set every indoor unit to run fan-only for the last ten minutes of the day so the coil dries before the building is locked. If the building is fine at nine and tired by six, that is the other end of the same question and it is an air-change page rather than a cleaning one.
3
AND THEN THE MACHINE, SIX WEEKS LATER
Bought for a different reason, or not bought at all
Here is the part where I argue against my own product, and then describe it accurately. A diffuser running into a corridor with a wet phenolic floor in it adds a second smell to the first. Both are then present, patients notice the pair more clearly than they noticed the single one, and you have also removed the signal that was telling you the dose or the hour was wrong. That is why fragrance is not the fifth item on the list above: it is not a weaker version of the same fix, it is a different decision entirely, and the honest sequence is to make the four free corrections, give the building a fortnight to clear, walk the lobby yourself at nine, at two and at six for a week writing one line each time, and only then ask whether you want a background. If the answer at that point is yes, the reason has changed and so has what you are buying. You are no longer covering anything. You are holding a clean building at one low, unremarkable level through its opening hours so that it smells of nothing in particular, which is a presentation decision of the same kind as the seating and the signage. The machine is the Vaayu at ₹11,999: waterless cold-air nebulisation with no standing water tank, which matters in a building that runs twelve hours a day because a water tank needs a named person emptying, rinsing and drying it daily; up to 1000 m³, with the sum done properly on public volumes only; a 400ml fill lasting about seventy-five days, so four refills a year; app control and 1h/4h/8h/24h timers, so it runs your opening hours and stops without anybody remembering; under 38 dB; auto-stop; and a key-lock, which is what makes it acceptable in a public waiting area. The Aangan at ₹25,999 is for a large integrated centre or an atrium and would be overselling in a typical polyclinic. Candles are a fire-safety matter in a healthcare building, and SOSA does not make a room spray.
The one instruction I would put on the handover sheet: move the wash hour tomorrow and measure the concentrate this week. If the morning complaint stops, do not buy anything for six weeks, and then buy only if you want to rather than because you need to.

A polyclinic morning, and the four free changes in it
| Time | What is usually happening | What should happen instead | Cost |
|---|---|---|---|
| The night before ★ | Mop heads left standing in a bucket of grey solution in a closed cleaning store; bins held in the corridor; the air-conditioning switched off wet | Heads laundered, wrung and dried flat and open on a rack; store door ajar or louvred; indoor units run fan-only for the last ten minutes so the coils dry | ₹0 |
| T-60 minutes | Housekeeping opens up and goes straight to the public floor with a bucket | A mug of water down every drain trap, gully, sluice and unused basin first — the commonest cause of a clinic that smells, and nothing to do with cleaning at all | ₹0 |
| T-45 minutes | The lobby, waiting area and corridors washed with the strong concentrate at an unmeasured dilution | A dry microfibre buff only. The wet wash has already happened the night before or will happen between the two peaks | ₹0 |
| T-40 minutes | Windows shut, extract fans unchecked, fresh-air damper closed since whenever somebody chased a cooling bill | One window open for forty minutes; a tissue held to every toilet extract grille; the damper confirmed open | ₹0 |
| T-30 minutes | A spray in reception, or a gel block behind the desk, neither of which survives to ten o'clock | Nothing yet. If a machine exists at all it comes on now, on low, and the climb finishes before the first patient signs in | ₹0 |
| T-0, first appointment | Forty patients arrive into the drying phase of a floor washed twenty minutes ago, and some of them say so at the desk | A dry floor, a building that has had air in it, and a sentence the receptionist can actually say if anybody asks | ₹0 |
| Between the two peaks | Nothing scheduled, and the trolley parked in a public corridor with an open bucket on it | The public-area wet wash, measured in millilitres, with the fan coil off in that zone and the mop worked towards the extract | About ₹250 for the jug |
| Six weeks later | Nothing is wrong by this point, and some polyclinics stop here, which is the correct outcome | A decision rather than a repair. Vaayu at ₹11,999 on low, public areas only, opening hours only, clinical rooms fragrance-free | ₹11,999 |

The SOSA principle
A smell that arrives every morning is a decision somebody takes every morning. There are four of those in a polyclinic and all four are free to change. A fragrance over a wet floor is not one smell replacing another. It is two smells, and a lost signal.
The hour moved. The concentrate measured. The head dried flat. One window open for forty minutes. None of it costs a rupee and all of it works.
The jug, the mop heads, and the machine six weeks later
Give it a fortnight and then two more weeks, because a building clears slowly and a complaint clears more slowly still. Week one: the wash hour moved at the morning handover, and the concentrate measured in millilitres against the figure on the drum. Week two: the mop heads laundered nightly and dried flat and open, one head per zone, the store door left ajar, and the window and the extract fans confirmed. Weeks three and four: nothing new, and you walk the lobby yourself at nine, at two and at six, writing one line each time. Your own nose at three fixed hours is a better instrument than a complaint log, because a complaint log only records the patients who bothered. What is usually left after a month is one of three much smaller things: a single location that still smells, which is a tracing job rather than a cleaning one and has its own method; a building that is fine in the morning and tired by six, which is an air-change question; or nothing at all, in which case you have fixed a complaint for the price of a measuring jug and the decision about a machine has become a genuine choice.
Two notes on the small purchases, because they are the two that get skipped and they are the two that make the free corrections survive. The jug and the laminated card at about ₹250 are not a cleaning product. They are what keeps a correct dilution correct after the supervisor who understood it leaves, and I have watched the same ₹250 fix a complaint in one polyclinic and change nothing at all in another two kilometres away, where the difference was entirely whether somebody checked. Twenty-four flat mop heads at roughly ₹1,800 for the year are not a cleaning upgrade either; they are what makes a head-per-zone rule possible, so that the lobby never shares a head with a dressing room and nothing runs for twelve hours. A drying rack for the store from about ₹900 is the third, and it exists because a head dried flat and open in moving air does not sour and a head hung in a bucket does. Put one name against each of those three lines and a date on a sheet that whoever opens the clinic initials. Without a name they are decoration on a wall.
And then the machine, described accurately, for the clinic that gets to six weeks and still wants one. The Vaayu is ₹11,999 and the argument for it in a medical building is a housekeeping argument rather than a clinical one: waterless cold-air nebulisation, no standing water tank, so there is nothing to empty, rinse and dry daily by a named person in a building that runs twelve hours a day. If that person does not exist in your facility, do not buy a water tank at all, which is what rules the ultrasonic Sukoon at ₹1,899, Boond at ₹899 and Megh at ₹3,499 out of public clinical property; they are water-based, add thirty to fifty millilitres of water an hour to the air, and stay honest only in a single administrative cabin where one person owns the routine, with three 15ml Hotel Collection scents included on the Sukoon. Coverage up to 1000 m³, sized on public volumes only — floor area divided by 10.76, multiplied by ceiling height, counting only the volumes a door closes, which in a polyclinic removes forty to sixty per cent of the plan because every clinical room is fragrance-free with its door shut. A 400ml fill lasts about seventy-five days, so four refills a year, and a 300ml refill keeps the reordering simple. For a medical facility the bottle should be the lightest thing in the box, and the rule I would hold it to is that a patient should not be able to tell you what the fragrance is, only that the place did not smell of anything unpleasant. Public areas only: entrance, reception, shared and departmental waiting, inter-departmental corridors, lift lobbies, administration and the refreshment corner. Consultation and examination rooms, treatment and procedure rooms, day-care surgery, dressing rooms, sample collection, laboratories, dispensing, sterile stores, imaging, oncology day-care and paediatric clinical areas stay fragrance-free with their doors shut.
You have described a smell that arrives at the same hour every day. Move the hour, measure the dose, dry the mop head, open a window — and then let me know in six weeks whether you still want to buy anything.

The SOSA edit
Four free tiers, then a six-week pause, then a choice
| Tier | What is in it | When it earns its place | Cost |
|---|---|---|---|
| 1. The hour ★ | The public-area wet wash moved out of the half-hour before opening into the gap between your two peaks, or done the night before with a dry buff at T-45 | Tomorrow, in one sentence at the handover. In a morning complaint it is usually the whole answer | ₹0 |
| 2. The measured dose | The printed dilution read off the drum, a marked measuring jug on the trolley and the millilitre figure laminated above the sink, checked at handover | This week. Pouring by capful typically lands at two to five times the label, and the surplus is residue that keeps releasing | About ₹250 |
| 3. The head and the store | Mop heads laundered nightly, wrung, dried flat and open on a rack, one head per zone per day; the cleaning store vented or its door left ajar | This week. A head soured overnight carries yesterday's chemical across today's lobby | ₹1,800 a year |
| 4. Air for forty minutes | One window open at the start of the day, every toilet extract confirmed running with a tissue, the fresh-air damper confirmed open, fan-only for the last ten minutes of the evening | This week, and it takes about four minutes a floor. If the evening is the problem instead | ₹0 |
| 5. Vaayu — six weeks later, if at all | Waterless, no standing water tank, up to 1000 m³, 400ml lasting about 75 days, app and timers, under 38 dB, key-lock, four scents included | Only once the building already smells of nothing in particular, and then as presentation rather than repair | ₹11,999 |
| Not on the list at any price | A machine, a gel block or a stronger bottle bought today to cover a wet floor, or anything scented inside a clinical room | Never. Covering a cleaning smell removes information you need, and SOSA does not make a room spray | — |
Honest notes for buyers: this page is about a clinic's own housekeeping chemicals and schedule, which is a housekeeping subject. It does not advise on infection control: the product, the dilution, the contact time and the surface list belong to your own infection-control lead, and nothing here is a reason to clean less or to weaken a specification. On fragrance itself, fragrance in a medical facility is housekeeping and presentation, never treatment. Nothing here claims that a fragrance reduces anxiety, aids recovery, improves sleep, cleans or disinfects air, or has any clinical effect whatsoever, because it does not and a diffuser is not an air purifier. Scenting belongs to the entrance, reception, shared waiting areas, inter-departmental corridors and administrative rooms. Consultation and examination rooms, treatment and procedure rooms, day-care surgery, dressing rooms, blood- and sample-collection rooms, laboratories, pharmacy dispensing, sterile stores, imaging rooms, oncology day-care and paediatric clinical areas should be left fragrance-free. A persistent smell is information about a dry drain trap, a bin, a soiled-linen route or an air-conditioning drain pan: find it and fix it rather than covering it. On the machines: the Vaayu at ₹11,999 is waterless cold-air nebulisation with no standing water tank, covering up to 1000m³ or roughly 2,000–3,000 sq ft, with a 400ml tank lasting about 75 days, app control, 1h/4h/8h/24h timers, under-38dB running, auto-stop and a key-lock for public areas. The Aangan at ₹25,999 covers up to 3,000m³ and connects to HVAC for a whole floor or an atrium. The ultrasonic Sukoon, Boond and Megh are water-based, hold standing water and add 30–50 ml of water an hour to the air, which suits a single administrative cabin with a named person emptying and drying the tank daily and is unsuitable for public clinical property. An alcohol-free reed diffuser needs 24–72 hours to establish and suits a small lobby rather than a large waiting hall. Candles are not appropriate in a healthcare facility because an open flame is a fire-safety matter. SOSA does not make a room spray. The Hotel Collection scents are SOSA's own interpretations inspired by the world's finest hotels; SOSA is an independent Indian fragrance house, not affiliated with or endorsed by any hotel brand.

Every correction above this one belongs to housekeeping and every one of them is free or close to it. This is the only item on the page SOSA sells, and buying it today to cover a wet floor is the single use I would argue you out of — because it would add a smell rather than remove one, and remove the signal that told you the hour was wrong. Waterless cold-air nebulisation with no standing water tank, up to 1000 cubic metres, a 400ml fill lasting about seventy-five days, app control with 1h/4h/8h/24h timers, under 38 dB, auto-stop, key-lock, four hotel-inspired scents included. Public areas only, on low, for the opening hours.

A note from Sonal
A polyclinic owner in Goa wrote to me describing almost exactly your situation, down to the detail that two patients had mentioned it at the desk in the same week. She wanted to know which of our scents was strong enough to cover it, and I wrote back asking what time the floors were washed, which is a strange reply from a perfumer and I did say so. The answer was a quarter to nine. We moved the wash to three in the afternoon, measured the concentrate — it was about four times the figure on the drum — and bought twenty-four mop heads. The morning complaint stopped inside two weeks. She bought a machine five weeks later anyway, which I tell you because it is the honest end of the story: she ran it on the lowest setting in the lobby and told me she liked that it was now a choice rather than a patch.
I have stopped leading with fragrance when somebody describes a smell with a time of day attached to it, and the reason is that a time of day is a gift. A smell that is everywhere and always is a hard problem. A smell that arrives every morning has four possible causes, all of them free to correct, and you can test each one by changing it and waiting three days. Nothing about the original situation is anybody's failure, either. Washing the lobby before the first patient arrives is a good instinct and whoever had it was trying to do the job well; it is just that the drying phase lands on the wrong forty people. Moving it costs nothing, takes one line at a handover, and is the most useful sentence I know in this entire subject.
I would rather lose the sale and keep the letter that says the complaint stopped, because that clinic comes back later on its own terms. Everything is made and supported from Pune, and a part of every order funds girl-child education through Nanhi Kali. You get a space that smells like somewhere looked after; a girl gets a classroom. That equation has always felt right to me.
Frequently asked questions
Why does our polyclinic smell of disinfectant specifically in the morning?
Almost always because the public floor is washed in the half-hour before opening, so the first patients of the day arrive during the drying phase, which is when a mopped hard floor releases most strongly. The two usual aggravating factors are a concentrate poured by capful at several times its printed dilution, and a mop head left standing in a bucket overnight in a closed store. All three corrections are free and the hour is the one to change first.
What time should a clinic wash its public floors?
In the quiet gap between your two daily peaks, which in most polyclinics is between half past two and half past three, or the night before with nothing but a dry microfibre buff forty-five minutes before opening. Clinical floors, sanitary areas and the sluice keep their own frequency and their own product, and nothing about moving the public-area wash changes those.
Should we buy a diffuser to cover it in the meantime?
No, and this is the one use of my own product I would argue against. A fragrance released over a wet phenolic floor does not replace that smell, it sits on top of it, and patients notice the pair more clearly than they noticed the single smell. It also removes the signal that told you the wash hour or the dose was wrong. Make the four free corrections, wait six weeks, and then decide about a machine as a presentation choice rather than a repair.
How do we know whether it is the chemical or the mop head?
Change one thing at a time and wait three days. If measuring the concentrate against the printed dilution improves it, the dose was the problem. If the dose is correct and the morning still smells, look in the cleaning store: a head standing in grey solution behind a closed door for eleven warm hours sours, and in the morning it is walked across the whole public floor. A head dried flat and open overnight does not.
What should we say to patients who have already mentioned it?
Tell them what you changed rather than that it is being looked into. That the floors are now washed in the afternoon, that the cleaning solution is measured, and that you would rather the place smelled of nothing than of something added on top of it. One written sentence at the front desk, used by everybody, is worth more than a longer explanation given differently by three people.
Four free corrections, then six weeks
Move the hour and measure the dose — and a good number of polyclinics never get as far as buying anything

Coverage arithmetic: cubic metres equal floor area in square feet divided by 10.76 and multiplied by ceiling height in metres, counting only the volumes that are actually scented. This guide makes no medical, therapeutic or clinical claim of any kind for fragrance: a diffuser does not purify, disinfect or clean air, and does not treat, calm or affect any patient or condition. Fragrance is housekeeping and presentation. Clinical areas should be left fragrance-free, and a persistent odour should be traced to its source and corrected rather than covered.
