Safety First

Before you begin the mould removal process, ensure that you take appropriate safety measures. Wear gloves, goggles, and a mask to protect yourself from mould. Adequate ventilation is crucial, so open windows and turn on fans to improve air circulation.

Scrubbing with Bleach

One of the most common methods to remove black mould is by using a solution of bleach and water. Mix one part bleach with four parts water and apply it to the affected silicone areas using a spray bottle or a sponge. Let it sit for about 15 minutes, then scrub the mouldy areas with a brush or scrubbing pad. Rinse thoroughly with water, ensuring that no bleach residue remains.

Vinegar and Baking Soda

If you prefer a natural alternative to bleach, vinegar and baking soda are effective options. Fill a spray bottle with distilled white vinegar and spray it generously on the mouldy silicone. Let it sit for an hour to break down the mould. Next, make a paste by mixing baking soda with a small amount of water. Apply this paste to the affected areas and scrub gently. Rinse the silicone thoroughly with water.

Hydrogen Peroxide

Hydrogen peroxide is another powerful mould remover. Fill a spray bottle with hydrogen peroxide (3% concentration) and spray it onto the mouldy silicone. Allow it to sit for about 10 minutes, then scrub the area with a brush or sponge. Rinse the silicone with water to remove any remaining mould and hydrogen peroxide residue.

Prevention is Key

To prevent black mould from recurring, it’s essential to address the underlying causes. Ensure proper ventilation in your bathroom by using an exhaust fan or opening windows after showers. Regularly clean your shower area and keep it dry to discourage mould growth. Consider replacing old or damaged silicone caulking with new silicone to create a tight seal and prevent moisture from seeping in.  


Removing black mould from your silicone shower is crucial for maintaining a clean and healthy bathroom environment. Whether you choose traditional options like bleach or prefer natural alternatives like vinegar, these methods can effectively eliminate mould and restore the appearance of your shower. Remember to prioritize safety during the process and take preventive measures to minimize the chances of mould regrowth. With consistent maintenance and proper care, your silicone shower can remain mould-free for years to come.
