Mold on the walls? Here's how to remove it forever - with simple solutions that work and without unnecessary complications

Mold is not only an aesthetic problem – although it ruins walls and mood – but can also affect health. It causes allergies, respiratory problems and is especially dangerous for children, the elderly and people with weakened immune systems. Therefore, it is crucial to detect it as soon as possible and learn how to effectively remove moldbefore she grows up to own your home.

How to remove mold: professionally but simply

1. First: protect yourself

Before you attack the wall, protect yourself. Mold is not innocent dirt – it contains spores that can cause health problems if inhaled.

You need:

• • Protective gloves (latex or nitrile)
  • Protective mask (ideally N95)
  • Eye protection glasses
  • Old clothes that you throw in the wash (or in the trash, if the situation is serious) after the event without any bad conscience

If the room is windowless, we also recommend a fan or at least an open door – ventilation is key.

2. Preparing the cleaning solution

The fastest and cheapest way to effectively remove mold is with a bleach solution. Let's not complicate things - you don't need a lab, just follow the proportions:

• • 1 tablespoon of dish detergent
  • ½ cup chlorine bleach
  • 1 cup warm water

Mix all of this together in a spray bottle. The bleach will kill the mold spores, and the detergent will help the solution “stick” to the wall so it stays on longer.

Important warning: Never mix bleach with ammonia, vinegar, or hydrogen peroxide – these are not home remedies, but potentially dangerous chemical reactions.

3. Cleaning process: from bottom to top

To effectively remove mold, it is important to spray or wipe the walls. from bottom to top. Why? Because it prevents the mold from spreading downwards due to gravity and creating new stains.

• • Soak the surface thoroughly, but be careful not to wet the walls (especially drywall - gypsum boards are not fans of bathrooms).
  • If the mold is high up, use a stable ladder or a mop with a soft sponge.
  • Let the solution sit – do not wipe it off immediately. Ideally, the surface should be independently air dry.

4. What if the mold remains?

Once the wall is completely dry, check to see if any dark spots remain. If so, repeat the process with a new mixture. Mold is stubborn, but usually subsides after 2-3 treatments.

However, if, even after repeated cleaning, you notice that the stains are returning, or that the smell of moisture remains – read on.

5. Alternative methods: for more sensitive noses

If bleach isn't your first choice (due to smell, sensitivity, or beliefs), you can also use:

• • Distilled vinegar: spray directly, leave on for 1 hour, then wipe and let dry.
  • Hydrogen peroxide (3%): effective for smaller areas, a bit slower, but lightens stains.
  • Commercial mold removers: check the ingredients – most contain bleach, just in a more “marketing guise”.
