Then should I increase the fragrance? No. SOSA's published stopper instruction is "Start tighter; open gradually until you find your level" and its published dosing card says two sprays scents a cabin for hours while five is a wasted bottle. More is the direction the manufacturer rules out.
Is there another reason not to? Yes. One occupant of this cabin cannot tell you the increase was too much, and cannot get out of the car. Anything about that animal's health is a question for your own veterinarian.
2. Then do not increase the amount. This is the fixed answer on this page. Washing takes a material out of the car. A fragrance puts a smell into the air. Those are opposite operations, and doing more of the second does not complete the first.
3. SOSA's own instructions point the other way. The direction your question points in is the one direction the manufacturer's own instructions argue against. SOSA's published dosing line, on the Oud and Mysore Orange Blossom pages, is "Two sprays = a beautifully scented cabin for hours. Five sprays = a headache and a wasted bottle." The hanging bottle's control is the stopper, and the published instruction for it is "Loosen for stronger throw, tighten for subtler. Start tighter; open gradually until you find your level." Start tighter. Open gradually. Those are SOSA's own words about its own product and they describe a dial you turn down first. Worth noticing, too, how that instruction expects you to find the level: by sitting in the cabin and noticing. In this cabin, one of the occupants cannot do that and cannot report the result, which is exactly why the tighter end of the stopper is where this page leaves it.
4. And the increase is not only your decision to make. One occupant cannot tell you it is too much and cannot leave the car while it is. Under-scent the cabin and a person is briefly disappointed. Over-scent it and the animal has no way to say so.
5. So the sequence is: wash, dry, air, then judge. Get in on a cool morning with nothing applied and smell the cabin honestly. Most readers find the question they arrived with has changed shape by then, and a good number find it has gone.
Nothing here is a claim about what a fragrance does or does not do to any animal, in either direction. SOSA has published no testing, no panel, no veterinary input and no species guidance, and your animal's health is a question for your own veterinarian.
Why the removable textiles come first
Worth getting out of the way first, because it decides what this page is able to recommend. SOSA does not sell one single thing that acts on the source here. No cleaner, no shampoo, no odour treatment, no washable seat cover, no brush, no vacuum and nothing at all made for a car that carries an animal. SOSA sells fragrance, in a bottle you hang up or a bottle you spray. So the most useful items in this answer are items you will buy from somebody else or already own, and a seat cover you can pull out and put in a washing machine is worth more to you on this problem than anything in the SOSA range.
The reason a blanket outranks everything else in this car is not that it smells worst. It is that it is the only source with an exit. Hair in a seam has to be lifted out of the car piece by piece. Material on a headrest has to be cleaned in place. A blanket can be picked up, carried indoors, washed properly, dried properly and brought back as a textile that is no longer part of the problem. That is a complete subtraction, and it is the only complete subtraction available to you.
The three ways to increase it, and why each is wrong here
Your question says increasing the amount, and there are exactly three ways to do that with what SOSA sells. It is worth laying all three out with the manufacturer's own published words next to them, because in all three cases those words argue against the move.
| The move | What SOSA publishes about it | Why it is the wrong move in this cabin |
|---|---|---|
| Loosen the stopper on a hanging bottle | "Adjust the stopper to control intensity. Loosen for stronger throw, tighten for subtler. Start tighter; open gradually until you find your level." On all eight scent pages | The published method for finding your level is to sit in the cabin and notice. One occupant cannot notice out loud, so the tighter end is where this page leaves it |
| Spray more often, or more sprays per application | "Spray once for a light reset. Two sprays for a stronger throw. Three sprays for a guest arrival reset." And on two pages: "Two sprays = a beautifully scented cabin for hours. Five sprays = a headache and a wasted bottle." | The manufacturer caps the useful amount well before five, and none of it acts on a blanket. You would be buying a second smell, not a solution |
| Buy a 15ML refill, ₹399 to ₹449 | "4 to 6 weeks per fill - the same as a full bottle." It fills the 12ml hanging bottle "fully, with a little to spare", and it fits the hanging bottle only | A refill buys more of the same operation on the same schedule. The blanket is in exactly the state it was in before you bought it |
| Buy a second bottle, or move to a deeper scent | Published character is per scent, not per format: Sandalwood medium-deep, Vetiver earthy-deep, Oud the deepest in the range | Depth is a character, not a capability. No SOSA page publishes anything about an animal's bedding, and no page claims an odour mechanism of any kind |
| Wash the blankets and the covers | Not a SOSA product and not a SOSA instruction. SOSA publishes nothing about it because SOSA sells nothing for it | This is the only row that changes the material. It is also the cheapest row, and it is the answer |
SOSA also publishes its own limit, and quoting it accurately is the reason the rest of this page can be believed. Under a heading reading Don't buy this if..., the Lemon, Sea Breeze and Mysore Orange Blossom pages each carry the bullet "You need a heavy cover-up for cigarette smoke or strong odours." Note exactly what that is. It is a negative-fit bullet telling a particular shopper not to buy. There is no published sentence anywhere in the range reading that a SOSA product does not act on odours, and this page will not manufacture one out of this bullet. But if what you are reaching for is a heavy cover-up, the manufacturer has already told you that this is not it. It sits on three of the twelve car pages; the Discovery Set publishes the clearing line with no such limit next to it at all.
Who the increase is being decided for
Now the part that makes this cabin different from every other cabin on this site. Everywhere else, the way to settle how much fragrance is enough is to ask the other people in the car. Here one of the occupants did not choose to get in, cannot get out, and cannot tell you that it is too much. That instrument simply does not exist, so it cannot be used, and the level has to be set some other way. The way it gets set on this page is by looking at the cost of being wrong in each direction. Under-scent the cabin and a human being is mildly disappointed for the length of one journey. Over-scent it and the occupant who cannot say so also cannot leave. Those two mistakes are not the same size, and the difference between them, rather than any claim about what fragrance does to an animal, is what sets the level here. It sets it downwards.
And the disclosure this page stands on, which is better said plainly than hinted at: SOSA has published nothing about animals. No testing in which an animal took part, no panel that included veterinary input, no species guidance and no instruction of any kind for a car that carries one. That is the entire record. It is why nothing written here makes a claim about what a fragrance does or does not do to any animal, in either direction. A brand that has not looked into something does not get to have a view on it, and dressing an absence up as reassurance would be worse than saying nothing.
There is one published line in the range about introducing a new scent gradually, and it is on the Refills page. It is addressed to children, elderly passengers and pregnant passengers. It names no animal, and this page is not going to extend it to one. A line written about people who can say when something bothers them does not transfer to an occupant who cannot, and stretching it would be exactly the kind of quiet upgrade this whole cluster exists to avoid.
Which leaves the part of the question that actually matters, and it does not belong to a fragrance company at all. Anything to do with your animal's health is a question for your own veterinarian - the one who has met the animal and knows its age, its history and its condition. Ask them directly whether a scented cabin is appropriate for yours, and take their answer over anything written by somebody who sells fragrance, this page included. That is not a disclaimer at the bottom of the page. It is the answer.
What to do instead, in order
What the range actually is, honestly described
One mechanical point, because it is the purchase people make when they decide they want more. The 15ML refill, ₹399 to ₹449 by scent, fits the 12ml refillable hanging bottle only. The spray bottle is published as currently single-use, with a refill programme described as in development, so a spray owner cannot top one up and should not be told otherwise. SOSA also publishes the spray's size two ways, 12ML in the product titles and 10ml in the longevity copy, and this page asserts neither of those as settled.
And since this page is about amount rather than character, the published numbers in one place. The published numbers, for arithmetic rather than for comfort. The hanging bottle is published at 4 to 6 weeks, approximately 28 to 42 days, of continuous diffusion. The spray is published at 3 to 4 hours per application, 100 sprays per 10ml bottle and about 50 days at two sprays a day. So a fragrance is consumed on a schedule. An animal is not on a schedule: whatever it brings into the car arrives again on the next journey, and again on the one after that. That mismatch, not the strength of anything, is why the smell outlasts the bottle every time.
| Product | What SOSA publishes about it | Why it is not your next step | Price |
|---|---|---|---|
| Car Hanging Freshener Refills 15ML | 4 to 6 weeks per fill, the same as a full bottle. Fills a 12ml hanging bottle fully with a little to spare, and fits the hanging bottle only. The spray is published as currently single-use with a refill programme in development | Because a refill buys more of the same operation while the blanket stays exactly as it is. Buy it when you have a clean cabin and an empty bottle, not now | ₹399 to ₹449 |
| Sandalwood 12ML | Published character medium-deep, 4 to 6 weeks for the hanging bottle, 3 to 4 hours per spray application. Publishes no odour claim at all | Because a different or deeper scent is a change of character, not a change of capability. Nothing in the range is published as acting on bedding | ₹479 |
| A washing machine | Not a SOSA product and never will be. SOSA sells no cleaner, no detergent, no cover and no pet product of any kind | It is your next step. This is the only row on this page that takes material out of the car | Not sold by SOSA |
Versailles
The honest answer to your question is half of your question. Yes, wash them. No, do not then increase the perfume. I know that is the opposite of what a fragrance company is supposed to say, and I would rather say it than sell you a refill that leaves you exactly where you started.
Look at our own instructions. The stopper line we print on every hanging bottle is start tighter, open gradually until you find your level. The dosing card on two of our pages says two sprays scents a cabin for hours and five is a wasted bottle. We wrote those. They describe a dial you turn down and then nudge upwards very slowly, and your question is asking me to approve a jump in the other direction.
The second reason is the one I would want someone to say to me. Turning it up is a decision about a passenger who cannot comment on it. We have published nothing about animals - no testing, no panel, no vet - so I have no business telling you what is fine for yours. Ask your own veterinarian. Wash the blanket this weekend, and leave the bottle where it is.
