Tea tree oil   . It has very powerful antifungal and antibacterial properties. Pour a tablespoon of this oil into a glass full of water and apply it directly to the surfaces using a cloth or sponge. This method is particularly effective against mold that builds up between bathroom tiles. No need to rinse.

Hydrogen peroxide   . Its power is not only limited to eliminating bacteria, but it is also capable of eliminating mold without generating toxic gases. Simply spray hydrogen peroxide directly on the mold and scrub with a toothbrush about 15 minutes later.

Salt   . Although it won’t eliminate mold that has already built up in the bathroom, it is great for preventing it. Table salt is a natural dehumidifier. Place a glass of rock salt in a corner of the bathroom to absorb excess moisture.
