Why does shower silicone keep going mouldy?
Common causes of mould staining and when replacement may be appropriate.
Shower silicone is regularly exposed to moisture, soap residue and limited ventilation. Surface mould can sometimes be cleaned, but staining embedded in deteriorated sealant may be difficult to remove.
Ventilation and drying after use can reduce recurring moisture. Where silicone is peeling, cracked or persistently stained, a professional cut-out and reseal may be appropriate. Investigate persistent leaks or dampness separately.
