Urine smell in your sofa: what to do first and when to stop DIY cleaning

Blot fresh liquid rather than rub

For fresh liquid, use a clean absorbent towel to blot rather than rub, as Crypton's spill guidance advises. This is an initial response, not a complete urine-removal procedure. As a precaution, pause further home cleaning if you are unsure whether a treatment suits your sofa. An assessment is needed to judge how much cleaning can help.

Check the care instructions before adding water or products

Check the care instructions for your sofa before adding products or water. Crypton warns against oversaturating its upholstery, scrubbing aggressively and leaving soap residue behind. Its guidance is specific to Crypton fabrics, not a wet-cleaning method for every sofa.

Pause if the smell persists or the fabric turns brown

If the smell persists, pause further DIY treatment as a precaution. Urine can reach the cushion filling and the sofa's structure, making odour removal difficult. Cotton or linen upholstery can turn brown after wetting and slow drying. IICRC advises professional help rather than DIY correction for this type of browning, but a brown mark alone does not establish its cause.

The cleaning method depends on the whole sofa

Prestige Care assesses the material, construction, condition and soiling to judge what cleaning can realistically achieve. Fibre composition and finish can also affect the method; the visible fabric is only part of the decision.

Cleaning may not be enough

IICRC's consumer guidance notes that even injected professional odour treatments may leave uncertainty about whether every urine deposit has been reached. Complete or permanent odour removal should therefore not be assumed.

IICRC notes that heavy urine contamination may require replacing cushion interiors alongside cleaning and deodorising their covers. This is a possible requirement, not a diagnosis of what your sofa needs.

Cleaning can remove soiling, but it cannot reverse fading, abrasion, colour loss, fibre damage or other changes that have become part of the material.

Have photos and a cleaning history ready

Note any DIY products or earlier professional cleaning: they may affect what can safely be done next. Have a short description and a few photos ready, including the whole sofa and affected areas. A photo of the manufacturer's label is useful if available, but not required to start. If the material or condition cannot be assessed confidently from photos alone, Prestige Care explains what else needs checking.
