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.
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.
Natural Cleaning Solutions
Vinegar and Baking Soda Paste
This powerful combo breaks down mould without harsh chemicals:
- Mix 1 cup white vinegar with 3 tsp baking soda
- Apply paste to mouldy areas with a cloth
- Let sit for 10 minutes
- Scrub with an old toothbrush
- Rinse with cool water
For stubborn stains, repeat the process. Vinegar kills 82% of mould species according to EPA studies.
Undiluted Vinegar Spray
For light mould:
- Spray vinegar directly on sealant
- Leave for 30 minutes
- Wipe clean with damp cloth
