Expert advice
Why does shower silicone keep going mouldy?
Understand moisture, ventilation and the difference between staining and failure.
Warm, damp surfaces and soap residue encourage mould growth. Even sanitary silicone can discolour when a bathroom stays wet for long periods.
Drying the enclosure, improving extraction and using compatible cleaners can help. Avoid damaging the bead with sharp tools or abrasive products.
If staining is embedded, or the silicone is lifting, replacement may be appropriate. Repeated mould can also indicate persistent condensation or a concealed moisture problem.
