White vinegar is an effective natural solution for removing mould from silicone sealant around showers, according to handyman Terry Alexander, founder of The Plumbero. The acidic properties of white vinegar break down mould spores without damaging the silicone or using harsh chemicals.
Why Mould Grows on Silicone Sealant
Silicone sealant is a porous material that traps moisture, creating an ideal environment for mould. Spores can penetrate deep into the silicone, making surface cleaning with bleach ineffective. Bleach only removes surface mould and cannot reach spores buried within the material, allowing regrowth.
How White Vinegar Works
White vinegar contains acetic acid, which kills mould spores by penetrating the porous silicone. Unlike chemical cleaners, vinegar is gentle and does not cause tearing or discolouration of the sealant. According to Terry Alexander, it is a natural and effective mould remover due to its acidic properties.
Step-by-Step Cleaning Guide
- Spray a generous amount of white vinegar onto the mouldy areas of the silicone sealant.
- Let the vinegar sit for at least one hour. For best results, leave it overnight to ensure all spores are killed.
- Open a window to ventilate the bathroom, as vinegar has a strong odour.
- After the waiting period, scrub the sealant with a bristled brush or old toothbrush. The loosened mould should lift away easily.
- Rinse the sealant with warm water and dry thoroughly with a clean cloth to prevent future mould growth.
Enhancing the Solution
For a more powerful cleaning mixture, combine white vinegar with baking soda and tea tree oil. This combination provides a longer-lasting fresh and clean appearance. Regular cleaning with white vinegar helps prevent mould accumulation on shower seals.
This natural method avoids harsh chemicals, making it safe for households with children or pets, and is cost-effective compared to commercial mould removers.
