Black mould is a form of microorganism that grows on damp surfaces. It is often found in bathrooms, on tiles, grout or behind shower walls. If left unchecked, black mould can spread and lead to structural damage in your home.
In addition to damage to the property black mould can be dangerous for health. Common symptoms of black mould include:
- Respiratory problems.
- Cough and throat irritation.
- Headache and fatigue.
- allergic reactions, such as itching and sneezing.
If you suspect you have black mould in your bathroom, it is important to act quickly.
What causes black mould in bathrooms?
Black mould thrives in damp and poorly ventilated environments, making bathrooms an ideal place for moulds to grow. Common causes include:
- High humidity after a shower or bath.
- Poor ventilation or no working bathroom fan.
- Leaks from pipes, showers or taps.
- Surfaces that remain damp for long periods.
To solve the problem in the long term, it is important to understand where the mould comes from and eliminate the root cause.
Step-by-step: How to get rid of black mould in the bathroom
1. identifying black mould
Black mould is recognised by its dark spots, often in joints, corners or on surfaces that do not dry quickly. Pay particular attention to areas where ventilation is poor.
2. protect yourself
Black mould can release spores that are harmful to breathe. When cleaning it is recommended to use:
- Protective mask.
- Gloves.
- Safety glasses.
3. use the right cleaning products
To effectively remove black mould, you can use:
- A mixture of vinegar and water (50/50).
- A mould remover from a shop.

- A simple option: Use ordinary detergent, water and a cloth.
Spray the solution on the affected area and leave it on for about 15 minutes before scrubbing with a brush. Rinse thoroughly with warm water.
4. Dry the area properly
After cleaning, it is important that the surfaces are completely dry to prevent mould from returning. Use towels or a dehumidifier if necessary.
