What the sofa smells of: cause and action
| Smell | Possible cause | What to do now | What you can expect |
|---|---|---|---|
| Sharp, like urine | cat, dog or child urine | blot, do not use hot water: urine smell in a sofa | may stay if the urine has reached the upholstery |
| Smoke | residue in the fabric and upholstery | do not smoke by the sofa: cigarette smoke smell in a sofa | may lessen, may come back |
| Musty, like a cellar | damp upholstery or mould | check the humidity: mould in a sofa | the cause of the damp must be dealt with; cleaning does not solve it |
| Like a spilt drink or food | liquid has reached the upholstery | blot, do not soak: stains on a sofa | depends on the liquid and the depth |
| Damp, after recent cleaning | the sofa has not dried yet | air it: how long a sofa takes to dry | usually you have to wait until it dries |
What to check before ordering
- Where the smell is strongest. Compare the seat, the backrest, the areas under the cushions and the underside of the sofa. Say so in the form.
- Whether there is a stain. A visible stain helps show where the liquid went. With cat urine, the area of smell can be up to three times larger than the soiled spot.
- What the label says. The letter W, S, WS or X sets what cleaning the fabric allows. If there is no code, test in a hidden spot before any cleaning.
- Whether the cause is still there. If people still smoke at home, the cat returns to the same spot or the room is damp, the smell may appear again after cleaning.
Why a smell may stay even after cleaning
Fabric is easier to clean than what lies beneath it. Foam can hold liquid and is hard to dry. If urine, a drink or water has reached the upholstery, cleaning the surface does not always reach the whole soiled area.
International Cat Care accepts this limit too: heavily soiled fabric should be thrown away where possible, because it stays attractive to the cat even after cleaning. No source gives a measured limit for foam, so we give no figures. Smoke is similar: the residue stays in the fabric, and the usual methods give only a short-lived result.
So the result depends on three things: the cause, the depth and whether the cause has been dealt with.
What is best avoided with a smelly sofa
- Do not soak the fabric. This can cause water rings, shrinkage, colour changes and damp upholstery.
- Do not use hot water on a fresh stain, as it can set the stain.
- Do not use ammonia-based substances after cat urine, because to a cat they smell of urine.
- Do not use chlorine bleach and strong substances, because they can change the colour.
- Do not take off zipped covers to wash them separately: they may shrink or change colour.
If a cat does this repeatedly, consult a vet first, because health reasons have to be ruled out. Cleaning does not solve a behavioural cause, and the cat may return to the same spot.
When cleaning is not the right job
If there is mould in the sofa, the moisture has to be dealt with, and you may have to replace the sofa. If the smell is in the whole room rather than in the fabric, it is no longer a furniture cleaning job: we work only with textiles. Bedbugs and fleas are another matter; that is a job for pest control.
How much sofa cleaning with smell treatment costs
Sofa cleaning costs from €35 for a two-seater, from €45 for a three-seater and from €50 for a corner sofa. Smell treatment is extra, from €15. The minimum order is €45: if the total is lower, you pay €45. Travel is included in Riga and up to about 15 km outside Riga; further out it is from €10.
The price depends on size, fabric, how dirty it is, smell and distance, and we agree it before work starts. Send a photo and the specialist will give you the price. More on accidents with pets: sofa cleaning after a cat or dog.
