Natural Ways to Remove Black Mould from Silicone Sealant

To remove black mould from silicone sealant naturally, mix equal parts of vinegar and water, apply it, let it sit for 30 minutes, then scrub and rinse clean.

Black mould on silicone sealant is a common problem in bathrooms and kitchens. The rubbery texture traps moisture, creating the perfect breeding ground for mould. Left untreated, it can spread and become a health hazard. This guide covers effective natural solutions to remove mould and prevent regrowth.

Natural methods to clean black mould from silicone

Why Mould Grows on Silicone Sealant

Silicone sealant provides ideal conditions for mould:

  • Traps moisture from showers and sinks
  • Creates warm, humid environments
  • Develops tiny cracks where water collects

Without proper ventilation, mould spores multiply quickly. Regular cleaning helps prevent buildup.
