How to Remove Black Mould From Bathroom Grout

Black mould in bathroom grout is a common problem that can be unsightly and unsanitary. Fortunately, there are several effective ways to remove black mould from bathroom grout and keep it from coming back.

1. Identify the Type of Mould

The first step is to identify the type of mould you are dealing with. Not all types of mould are black, and some types may require different cleaning methods.

2. Ventilate the Bathroom

Mould thrives in moist environments. Before you start cleaning, open windows or turn on a fan to ventilate the bathroom and reduce moisture levels.

3. Use a Bleach Solution

Bleach is a powerful disinfectant that can kill mould spores. Mix 1 cup of bleach with 1 gallon of water in a spray bottle. Apply the solution to the affected grout and let it sit for 15-20 minutes. Scrub the grout with a brush and rinse thoroughly with water.

4. Use a Commercial Mould Remover

There are several commercial mould removers available at hardware stores. Follow the instructions on the product label carefully.

5. Use Hydrogen Peroxide

Hydrogen peroxide is a natural bleaching agent that can be used to kill mould. Apply hydrogen peroxide to the affected grout and let it sit for 10-15 minutes. Scrub the grout with a brush and rinse thoroughly with water.

6. Use White Vinegar

White vinegar is a natural acid that can kill mould spores. Apply white vinegar to the affected grout and let it sit for 30 minutes. Scrub the grout with a brush and rinse thoroughly with water.

7. Use Baking Soda

Baking soda is a natural deodoriser and can help to remove mould spores. Make a paste of baking soda and water and apply it to the affected grout. Let it sit for 1-2 hours and then scrub with a brush and rinse thoroughly with water.

8. Preventative Measures

To prevent mould from coming back, keep the bathroom well-ventilated and clean. Use a squeegee to remove excess water after showering or bathing. Seal the grout lines with a mould-resistant sealant.
