What materials will you need?

You will need white vinegar or bleach, baking soda, water, a spray bottle, a bowl, and an old toothbrush or a scrubbing brush. You will also need rubber gloves, a plastic scraper, and paper towels or a cloth.

Always ensure safety first

Wear rubber gloves to protect your skin from the cleaning solutions, and ensure the area is well-ventilated. First, wipe the area with a damp cloth to remove any surface dirt or debris and apply the cleaning solution. Fill a spray bottle with white vinegar and spray directly onto the mouldy silicone sealant. Let it sit for at least one hour to allow the vinegar to penetrate and kill the mould.

Can you use bleach?

Mix one part bleach with ten parts water in a spray bottle and spray the solution onto the mouldy area. Let it sit for about 15 minutes. After allowing the solution to sit, use an old toothbrush or a small scrubbing brush to scrub the mould off. Wipe the area with a damp cloth to remove any residue from the cleaning solution and mould.

What can you do if the mould persists?

If the mould persists, create a paste using baking soda and water. Apply the paste to the affected area and let it sit for 10 to 15 minutes. Scrub the area again with the toothbrush or scrubbing brush. Rinse with water and wipe clean. Use paper towels or a clean cloth to thoroughly dry the area.
