How to remove black mould

There are a few ways to remove black mould from silicone sealant around windows. The following methods are all effective, but some are more labor-intensive than others.

Method 1: Vinegar and baking soda

Step 1: Make a paste by mixing white vinegar with baking soda

Pour enough vinegar onto the black mould to form a thick paste. Then, sprinkle baking soda on top of the vinegar and mix together until you have a thick paste.

Step 2: Apply the paste to the black mould and leave it to sit overnight

Apply the paste onto any black mould that you find around your windows. Then, cover it with an old towel or cloth and leave it to sit overnight.

Step 3: Remove the residue the next day with a wet sponge

Remove the old towel or cloth to find the black mould covered in a powdery substance in the morning. Using a wet sponge, begin to scrub away at this powdered mixture until all black mould has been removed.

Method 2: Toothpaste and baking soda

Step 1: Apply toothpaste onto the affected areas

Apply enough toothpaste onto the affected areas of your silicone sealant to form a thick layer. This is similar to how you would apply toothpaste to a toothbrush.

Step 2: Leave the toothpaste to sit for 30 minutes

Leave the toothpaste to sit for at least 30 minutes. This will give it enough time to break down the black mould.

Step 3: Remove the toothpaste with a wet sponge

Using a wet sponge, gently scrub at the black mould until it has broken down.

Method 3: Hydrogen peroxide

Step 1: Pour hydrogen peroxide onto a cloth and apply it to the mould

Pour hydrogen peroxide onto a cloth and apply it directly to any black mould that you find around your windows.

Step 2: Leave the hydrogen peroxide to sit for at least 30 minutes

Leave the hydrogen peroxide to sit for at least 30 minutes. This will give it enough time to break down the black mould.

Step 3: Remove the hydrogen peroxide with a wet sponge

Use a wet sponge to remove all the hydrogen peroxide around your windows. This will also remove any black mould that was left behind.

Whichever method you choose, be sure to repeat the process as necessary until all of the black mould has been removed. If the mould returns after a few days, repeat the process.
