There are several ways to remove mould, including commercially available anti-mould sprays or even white vinegar that you might already have in your pantry. You’ll also need a brush to scrape the mould off the walls.
If you’re using a mould spray from the shops, simply follow the instructions on the packaging. Make sure you wear gloves and eye protection to prevent contact with mould spores. Mould can be dangerous if inhaled.
If you’re using white vinegar instead, it’s usually a good idea to firstly do a spot test on your walls. This is to make sure the vinegar won’t also stain or damage them.
If you’re happy with the results of the spot test, you can go ahead and apply the vinegar to the mouldy areas. You can be generous with the vinegar here. Be sure to leave it on for an hour before scrubbing the mould away with your brush and some warm water.
Once you’ve removed the mould, leave the wall to dry out for a couple of hours.
Don’t mix your vinegar with bleach or apply one on top of the other when trying to clean your bathroom. This can create extremely dangerous chlorine gas that can burn your eyes, mouth and lungs.
