Mould is one of the most persistent household nuisances in the UK, appearing on tiles, shower screens and silicone sealant just when you think you’ve cleaned it all away.
Experts say the solution may not be stronger chemicals or expensive gadgets, but an everyday item costing as little as 80p: a simple bathroom squeegee.
In most homes, black mould is caused by common mould species such as Cladosporium or Aspergillus, rather than the more dangerous types often feared. It thrives in warm, damp conditions, feeding on moisture that settles on cold or poorly ventilated surfaces.
Black mould is often called “creeping” because it appears to slowly spread along grout lines, corners, and sealant, returning even after cleaning. This is because wiping away surface spores does not remove the damp conditions that allow it to grow.

Symptoms of exposure can include irritation of the eyes, skin and throat, and it can trigger asthma or allergies in sensitive individuals, although it is rarely dangerous for healthy adults.
How an 80p squeegee can help
A damp and mould expert at property maintenance firm Aspect said: “Contrary to popular belief, it’s not about how often you clean, and using stronger products won’t stop mould from returning. Unless the conditions that allow mould to grow are addressed, it will keep coming back.”
By keeping a simple squeegee in the shower, householders can wipe down tiles, shower screens and sealant after bathing. This removes surface water before it has a chance to settle, cool and feed mould spores.
The routine takes less than a minute but significantly reduces humidity on bathroom surfaces, particularly during winter when windows are shut and extractor fans may struggle.
Aspect advises combining this small step with proper ventilation. Extractor fans should run for 15% to 30% of an hour after showering, and opening the bathroom door can help moist air escape into drier parts of the home.
Damp towels left lying around should also be avoided, as wet fabrics release moisture back into the air, creating conditions perfect for mould to return.
While bathroom use is the most common cause of mould, Aspect warns that persistent black mould may indicate hidden leaks behind walls or under floors. In such cases, a professional leak detection expert should be called in.
For many households, however, keeping an 80p squeegee within reach and wiping down damp surfaces regularly could be enough to stop black mould creeping back.
