A musty smell in fabric furniture is one of the more common complaints we hear from clients, and it's usually a sign of something specific happening within the material rather than just general dirtiness.
What causes the smell
Musty odours typically come from bacterial growth within fabric fibres, often triggered by trapped moisture, whether from spilled liquid, humidity, sweat, or pets. Unlike surface dirt, this bacterial activity happens within the material itself, which is why surface cleaning or air fresheners rarely resolve it for long.
Why masking doesn't work
Fabric sprays and air fresheners cover the smell temporarily but don't address the bacteria causing it, which means the odour tends to return, sometimes stronger, once the masking scent fades. This is the most common reason households end up booking a professional clean after trying DIY solutions first.
How professional deodorising treatment works
Our steam extraction process combined with a targeted deodorising treatment addresses the bacteria at the source, within the fabric fibres, rather than just treating the surface. This produces a longer-lasting result than surface sprays or attempts at spot cleaning.
When the smell might indicate something more
Persistent musty smells that return quickly after cleaning can sometimes point to an underlying moisture issue, such as furniture placed against a damp wall or in a poorly ventilated room. In these cases, addressing the room's ventilation alongside the clean gives a more lasting result.
Prevention going forward
Allowing furniture a little space from external walls, using a dehumidifier in particularly damp rooms, and addressing spills promptly rather than letting them soak in all help reduce the chance of musty odours developing again after a clean.
