Fabric absorbs fragrance exactly the way it absorbed the smell you are trying to get rid of
After, always. Scenting a loaded fabric reservoir does not cover anything — it gives the reservoir a second thing to hold and release.
The short version
The answer
Sorption is not selective. A cushion cannot tell a cooking molecule from a jasmine one; it takes both in and gives both back.
The mechanism
Fabric holds everything
Scenting before a wash also wastes the fragrance outright. Whatever the fabric absorbed goes down the drain with the detergent.
The practical waste
Straight down the drain
The visitor test settles the argument. Nobody smells fragrance over a source; they smell both at once, which reads worse than the original.
Why it backfires
Two smells, not one
Clean fabric turns from a liability into an asset. It holds your chosen scent gently and re-releases it all day, which is free consistency.
The reason to wait
The reservoir works for you

Founder Diaries · Why does my home smell like this?
By Sonal Sahani · ISIPCA Versailles 9 min read Updated August 2026
After. There is no interesting version of this answer, and I sell the fragrance. The reason is not etiquette or thoroughness, it is physics: a fibre cannot tell the difference between a cooking molecule and a jasmine one. Sorption is completely indiscriminate. Put fragrance into a room with a loaded sofa and the sofa absorbs the fragrance too, then spends the next several days handing back both. And if the fabric is about to be washed, everything it absorbed goes down the drain with the detergent.
Quick answers — read this first
Reason one: fabric absorbs fragrance exactly as it absorbed the odour. A loaded reservoir given a second load releases both.

Reason two: scenting before a wash is pure waste — the fragrance the fabric took up leaves with the wash water.

Reason three: nobody perceives fragrance as covering a smell. A visitor gets both at once, which reads worse than the original problem on its own.

Reason four: once fabric is clean, it becomes an asset — it holds your chosen scent and re-releases it gently for hours. That only works if it is empty first.
The short answer
Short answer: After, without exception. Fragrance is additive, never subtractive — it adds pleasant molecules and removes nothing. Applied to a room with loaded soft furnishings, it is absorbed by the same fibre holding the stale note, so the reservoir stores and re-releases both. Applied before a wash, it is simply removed by the wash.
The one exception people ask about: There is not one, but there is a sequencing nuance. If you are cleaning in stages over a weekend, wait until the last item is clean and dry before you start the diffuser. Scent introduced halfway through gets absorbed by whatever is still dirty and by whatever you have just washed, which muddles both.
What to do instead while you clean: Ventilate. Five to ten minutes of cross-ventilation with two openings on opposite sides moves more air than an hour with one window, and a closed flat only exchanges 0.2 to 0.5 of its air an hour. Then, once everything is clean and fully dry, start the ambient layer — a reed diffuser from ₹749 or the Sukoon at ₹1,899.
Straight answer
Should I use home fragrance before or after cleaning sofas, curtains and rugs?
1. After. The fabric cannot tell the difference. Sorption is a physical process and it is entirely indiscriminate. The same pores and fibre surfaces that took in cooking aerosol, body odour and damp will take in the fragrance you add, at the same time, by the same mechanism. You are not covering the reservoir; you are loading it further. The sofa then re-releases both for days, in a mixture neither of you chose.

2. Scenting before a wash is money down the drain. If curtains are going into the machine on Sunday, any fragrance those curtains absorbed during the week leaves with the wash water. The same is true of cushion covers, throws and bedding. There is no version of this where the fragrance survives the cleaning, so you have paid for evaporation and laundry.

3. It reads worse to anyone walking in. People imagine fragrance sitting on top of an odour like a lid. That is not what a nose does. A visitor arriving into a scented room with a live source perceives two distinct things at once and the combination is more unpleasant than the original, because it also reads as an attempt to hide something. The original stale note at least reads as neglect; the combination reads as concealment.

4. It destroys your own ability to tell whether cleaning worked. Halfway through a weekend of washing covers and airing cushions, the only reliable measurement you have is your first breath back into the room after thirty minutes outside. Start a diffuser and that measurement is gone — you cannot tell whether the room improved or whether you simply added something louder. Keep the room unscented until the cleaning is finished and verified.

5. Wait, and the fabric starts working for you. This is the part worth waiting for. Clean porous material holds a pleasant scent as readily as it held the stale one and gives it back gently over hours, which is exactly the mechanism behind a home that smells consistent rather than intermittently perfumed. A reed diffuser or a Sukoon in a room with clean fabric performs noticeably better than the same product in a room with dirty fabric.

TL;DR: after, always. Fabric absorbs fragrance by exactly the same mechanism it absorbed the odour, so scenting a loaded sofa or curtain gives it a second thing to store and hand back. Scenting before a wash also wastes it entirely. Clean and dry everything first — clean fabric then holds your scent instead of fighting it.
SOSA reed diffusers, five scents
The step after everything is dry
SOSA reed diffusers From ₹749
Start this when the last item is clean and fully dry, not before. A SOSA reed diffuser then has clean fabric to work with, which is when it performs best — 50ml from ₹749 for 6–8 weeks, 130ml from ₹1,249 for 14–18, six fibre reeds included. Composed and made in India, in Pune.

Why sorption does not discriminate

The reason fabric is a reservoir in the first place is that its internal surface area is enormous relative to its size, and volatile molecules that touch that surface tend to stay on it. That process has no preferences. It does not evaluate whether a molecule is pleasant. A cushion cover exposed to fried onion and to Kashmir lavender takes up both, at rates that depend on the molecules and the fibre rather than on anyone's intentions. Everything true of odour absorption is equally true of fragrance absorption, and that single symmetry is the entire argument for cleaning first. It is also, incidentally, the reason home fragrance works at all in a clean room — the fabric holds and slowly returns what you put in.

The second half of the argument is about what a nose actually does with two smells at once. Perception does not work like painting over a wall. Presented with a stale background and a rose fragrance, you do not perceive rose; you perceive a specific and rather unpleasant third thing, and you perceive it as an attempt. This is why scented-over cooking smells and scented-over bathroom smells are so recognisable and so disliked. It is also why the honest advice in this whole category has to be the same regardless of who is giving it: fragrance is additive, never subtractive. It puts molecules in. It takes none out. Anything sold to you on the basis that it removes, neutralises or eliminates an odour by scent is being described wrongly.

Three ways scenting first actively backfires

1
BACKFIRE ONE · YOU LOAD THE RESERVOIR TWICE
The sofa now holds two things
SOSA reed diffusersStep fourFrom ₹749Run a diffuser in a living room with a saturated sofa and curtains and the fragrance does not sit in the air waiting to be admired. Most of it is absorbed by the porous material in the room, because that is what porous material does. You now have a reservoir holding both the original odour and the new fragrance, and it will release them together for days. The mixture is not something you chose and it cannot be undone by switching the diffuser off, because the fabric carries on regardless. This is the single most common way people make a room worse while trying to improve it.
The tell: the room smells of your fragrance and something underneath it, and turning the diffuser off changes very little for the first few days.
2
BACKFIRE TWO · YOU PAY FOR NOTHING
A wash removes what you just added
The economics are as clear as the physics. A 50ml reed diffuser runs six to eight weeks; a 130ml runs fourteen to eighteen. If curtains, covers and throws are going into the machine this weekend, every molecule of that fragrance which was absorbed by those textiles is about to be washed out. You will have spent part of a bottle scenting fabric that is about to be laundered. Doing it in the other order costs exactly the same and the fragrance goes into material that will hold it for weeks rather than hours.
The rule: if it is going in the machine within a fortnight, do not scent the room it lives in until after it comes out.
3
BACKFIRE THREE · YOU LOSE YOUR MEASUREMENT
And with some smells, that matters a great deal
The only honest test available to you is the first breath back after thirty minutes outside, because olfactory adaptation is essentially complete in about twenty. Fragrance destroys that instrument. Worse, it hides signals you actually need: a musty note tells you there is moisture somewhere and possibly mould, which is a health issue and not an odour problem; a sewer note tells you a P-trap has dried out or a seal has failed, which is a plumbing job; a gas or burning smell is an emergency. Covering any of those with fragrance is not a cosmetic decision. Deal with them, then scent.

Symptom to cause: when people ask this question

The reason people want to scent first is usually one of the situations below. Each has a better answer than fragrance, and in two of them fragrance is genuinely the wrong tool entirely.

The order-of-operations table
Why you want to scent first, what is really going on, and what to do
What you notice Most likely cause How to confirm it What actually fixes it
Guests arriving in two hours and the sofa smells ★ A live fabric reservoir with no time for a proper reset Press a cushion hard and smell what comes out of the foam Cross-ventilate ten minutes, sun the cushions, run scent last for the final hour
Mid-way through a weekend of cleaning Half the reservoirs clean, half still loaded — the worst moment to scent Judge on the first breath back after thirty minutes outside Finish and dry everything, verify the room, then start the diffuser
Curtains and covers are going in the machine this week Anything the fabric absorbs now is about to be washed out Check what is on the laundry list for the next fortnight Wait until they are back on and dry, then start scenting
You want to know whether the cleaning worked Fragrance removes your only measuring instrument Leave for thirty minutes and judge the first breath back, unscented Keep the room unscented until it passes that test
A musty note you were hoping to cover Moisture, and possibly mould — a health issue, not an odour Check walls behind furniture, window reveals, under sinks, ceiling corners Find the moisture source and remove the growth. Do not fragrance this.
A drain-like note you were hoping to cover A dry P-trap or a failed seal — a plumbing job Run water down every drain you rarely use and see if it stops Restore the water seal or get the trap fixed. Fragrance is not the answer.
If none of these fit: the honest sequence is always source, air, fabric, then scent. If you find yourself wanting to reverse the last two steps, it is worth asking what the fragrance is actually being asked to do.

Where fragrance comes in — the moment everything is dry
The SOSA principle
A fibre cannot tell your fragrance from your problem. It stores both.
Which is why the order is not a matter of thoroughness but of physics — and why a scent added to clean fabric performs noticeably better than the same scent added to dirty fabric.

The correct sequence, hour by hour

While you are cleaning: ventilate, do not scent. Open two windows on opposite sides for the duration, or put a fan in a window blowing outwards, which pulls the room's air out behind it rather than pushing street air in. A closed flat exchanges only about 0.2 to 0.5 of its air an hour and cross-ventilation takes that to 3 to 8, so this is doing far more work than anything you could add. Cleaning also raises humidity — wet floors, damp covers, a running machine — and humidity both slows drying and makes odour easier to perceive, so air movement is the priority all day.

When you have finished: wait for dry, then verify. Everything must be completely dry before you do anything else — covers refitted onto damp foam and curtains rehung with damp headers create worse problems within days, especially in monsoon. Once the last item is dry, run the honest test: leave the flat for thirty minutes, come back, and judge your first breath. If the room reads neutral, you are done and ready. If it does not, something is still loaded, and adding fragrance now would only hide the fact.

Then, and only then, start the ambient layer. With genuinely clean fabric in the room, both products work better than they otherwise would, because the same porous material that was fighting you now holds your scent and returns it slowly. A reed diffuser from ₹749 is the choice for a room that should simply always smell settled with nothing to operate; six reeds for full strength, four in a bedroom, two or three in a small bathroom, and replace the reeds rather than the liquid when the throw drops, since reeds clog over months. The Sukoon at ₹1,899 with 3–6 drops of a water-based Hotel Collection scent from ₹299 covers roughly 270–320 sq ft and gives you a switch instead. The two liquids are not interchangeable — oil-based reed fragrance does not go in a machine, and water-based machine fragrance does not go in a reed bottle.

Scenting a dirty sofa does not cover the smell — it gives the sofa a second thing to give back.

The order that works

This blog is really about one line in the table below: fragrance is step four. Everything above it costs nothing, and skipping any of it makes step four perform worse.

Why fragrance is fourth
Source, air, fabric, then scent
Step What to do When Cost
1. Remove the source Deal with any live source first — a wet trap, a damp wall, a drain — because scent over a source reads worse Before anything else ₹0
2. Move the air Cross-ventilate throughout the cleaning; a fan blowing out of a window clears a flat fastest Daily, five to ten minutes ₹0
3. Deal with what holds it Wash and fully dry every cover, curtain and throw; air the cores; verify with the thirty-minute test Weekly to monthly ₹0
4. Then the always-on layer ★ A SOSA reed diffuser — a constant background that clean fabric will hold and re-release gently all day 50ml 6-8 weeks · 130ml 14-18 from ₹749
5. Or the on-demand layer Sukoon with a Hotel Collection scent — scent on demand once everything is dry; covers roughly 270–320 sq ft Run it when you want it ₹1,899
Honest notes before you buy: the order above is not padding, it is the whole method. Home fragrance is an additive layer — it puts pleasant molecules into the air, it does not remove unpleasant ones. Scenting over a live odour source gives you both smells at once, which reads worse than the original problem, and it removes the signal that was telling you something needed attention. Three causes in particular are never a fragrance problem: visible or suspected mould, which is a health issue and needs the moisture source found and the growth removed; a drain or sewer smell, which usually means a dry P-trap or a failed seal and is a plumbing job; and a gas-like or burning smell, which should be treated as an emergency, not an odour. Persistent damp in a wall or ceiling is a building fault and needs a professional. Once the room is genuinely clean and dry, SOSA reed diffusers run oil-based fragrance with no electricity, while the Sukoon (₹1,899) runs the water-based Hotel Collection — the two liquids are not interchangeable. Reed fragrance is composed and made in India, in Pune; both are phthalate-free and composed to IFRA standards for home diffusion, not for skin or ingestion. A portion of every order supports girl-child education through Nanhi Kali.

The on-demand layer
SOSA Sukoon · 500ml ₹1,899
Once the room is clean and dry, the Sukoon at ₹1,899 gives you scent with a switch — run it for an hour before people arrive rather than all day. It takes 3-6 drops of the water-based Hotel Collection (from ₹299) and covers roughly 270-320 sq ft. A reed diffuser is the opposite trade: no switch, no effort, always on.

A note from Sonal

The commercially convenient answer to this question would be "either, why not both". The correct answer is after, and it costs me sales to say so, because a customer who scents a loaded room concludes that the fragrance was weak and buys nothing again. A product used in the wrong order fails, and the person blames the product. I would rather explain the order once.

The symmetry is the thing to remember. Everything that makes fabric a problem — the porosity, the surface area, the slow two-way release — is the same property that makes home fragrance work at all. A clean sofa is not a neutral object; it is a slow-release device that holds whatever you give it. Give it the stale version and that is what you get back. Give it the clean version and you have a room with a consistent character for very little ongoing effort.

And there are three smells I will not sell fragrance for, in any order. Mould or visible damp, which is a health issue and needs the moisture found and the growth removed. A drain or sewer smell, which is a dry trap or a failed seal and needs a plumber. And anything gas-like or burning, which is an emergency, not an odour. If your room smells of any of those, close this page and deal with it. A portion of every order funds a girl's classroom through Nanhi Kali.

Frequently asked questions

Should I use home fragrance before or after cleaning soft furnishings?
After, always. Fabric absorbs fragrance by exactly the same mechanism it absorbed the original odour, so scenting a loaded sofa, curtain or rug simply gives it a second thing to store and release. If the item is about to be washed, the fragrance it absorbed is removed by the wash anyway. Clean everything, dry it completely, verify the room is neutral, then start the diffuser.
Does fragrance remove or neutralise a smell?
No. Home fragrance is additive: it adds pleasant molecules to the air and removes nothing at all. No product from any brand changes that, whatever the packaging says. What fragrance genuinely does well is give an already clean and neutral room a consistent character, which is a real and worthwhile job — but it is the last step, not a substitute for any of the earlier ones.
Can I spray fragrance on my sofa or curtains?
Better not to. Fabric absorbs it into the fibre, so it is stored and re-released alongside whatever else the fabric is holding, and on upholstery it also puts liquid into foam that then dries slowly. Keep scent in the air rather than on the material. If the fabric is loaded enough that you want to spray it, what it actually needs is a wash, a vacuum and some sunlight.
What should I do about the smell while I am still cleaning?
Ventilate rather than scent. Open two windows on opposite sides for five to ten minutes at a time, or put a fan in a window blowing outwards so it pulls the room air out. A closed flat exchanges only about 0.2 to 0.5 of its air an hour; cross-ventilation takes that to 3 to 8. That is doing far more than any product could, and it keeps your nose available for judging progress.
When exactly can I start the diffuser?
When the last item is completely dry and the room passes the honest test — leave for thirty minutes, come back, and judge your first breath. If it reads neutral, start. A reed diffuser from ₹749 gives a constant background with no electricity, at six reeds for full strength or four in a smaller room. The Sukoon at ₹1,899 with a Hotel Collection scent from ₹299 gives you a switch instead; the two liquids are not interchangeable.
The moment everything is clean and dry
Clean first — then let clean fabric hold what you chose
SOSA reed diffusers composed and made in Pune, 50ml from ₹749 for 6–8 weeks or 130ml from ₹1,249 for 14–18, six fibre reeds included. Or the Sukoon at ₹1,899 with a Hotel Collection scent from ₹299 when you want a switch. Neither removes an odour, and both work noticeably better in a room whose fabric is already clean.
