Can Mouldy Silicone Be Cleaned?
Mould on bathroom sealant is one of the most common problems homeowners experience. While surface staining can sometimes be improved with cleaning products, mould that has penetrated deep into the silicone usually cannot be fully removed permanently.
This is why black staining often returns shortly after cleaning.
When Silicone Should Be Replaced
Sealant replacement is usually recommended when:
- mould keeps returning
- silicone is cracked or peeling
- joints are separating
- water can reach behind surfaces
- the sealant looks permanently stained
Replacing failed silicone properly helps restore waterproof protection and improves the overall appearance of the bathroom or kitchen.
Why Replacing Sealant Properly Matters
Applying fresh silicone over old mouldy sealant rarely solves the problem long-term. Existing contamination and weak adhesion underneath can quickly lead to further failure.
Professional removal and replacement creates a cleaner finish and more durable result.
