Acting quickly on a fresh stain, understanding why some odours come back and knowing when a professional treatment really helps: field notes from Pronett67 in Strasbourg, without miracle promises.
A stain on a sofa, mattress or rug is rarely just a visual accident. Depending on the liquid, the fabric and how long it has been there, it may have soaked into the foam, worked into the weave or altered the fibre itself.

A persistent smell in a sofa is not fixed with a fragrance. Identify the source, air the room, remove debris, avoid risky mixtures — and treat the cause, not just the symptom.
In the first minutes, a fresh stain sits mostly on the surface. The liquid has not yet migrated into the foam and has not dried into the fibre. After a few hours, the water evaporates but the pigments, salts and proteins stay behind and set. That is why a coffee stain forgotten over a weekend behaves very differently from one dealt with within the hour.
On sofas and mattresses, thickness makes it worse: the foam absorbs part of the liquid and slowly releases the residue. A stain that looks gone from the surface can reappear days later as a halo.
The first good reflex is not to clean — it is to look. A biological stain (urine, blood, vomit) is not treated the same way as a food stain (coffee, wine, grease). A product suited to one may permanently set the other.
These stains contain proteins. Use cold water only — never hot, which coagulates proteins and sets them into the fibre. Old urine often needs an enzyme-based product to break down the ammonia salts responsible for the smell.
These are mostly pigment stains. A quick blot with a white absorbent cloth already helps a lot. On a light-coloured sofa, avoid off-the-shelf stain removers without a discreet test: watermarks are a real risk.
These stains need a solvent suited to the fabric. A slightly damp microfibre cloth and a mild soap sometimes handle a recent mark, but on delicate fabrics DIY can dull the treated area.
An odour that 'returns' is almost never a bad clean — it is a deeper contamination. Urine soaks into the foam, tobacco clings to fibres and covers, cooking oils build up on fabrics over the months. A spray deodoriser masks; it does not treat. Extraction cleaning removes embedded molecules and neutralises much of the odour — without guaranteeing full elimination on the oldest cases.
Most watermarks appear when a fabric dries unevenly, or when a household product leaves a lighter residue as it dries. On microfibre in particular, this can create a visible ring far larger than the original stain.
On delicate fabrics — microfibre, alcantara, wool, viscose — a test on a hidden area is essential. We always do this before intervention, and we recommend doing it at home too, even with a product described as 'gentle'.
Most of our clients in Strasbourg and the Eurométropole send us a photo on WhatsApp. A clear shot in natural light — one wide view and one close-up — usually tells us whether the result will be clean, partial or uncertain. That avoids a pointless visit and lets us send a clear estimate.
