Tile joints in floors, bathrooms and kitchens often lose their whiteness and become black. In humid environments, they also become covered in dark, smelly mold. Furthermore, the spaces between the tiles, which are usually slightly indented, facilitate the accumulation of dirt, blackening the joints.
To eliminate mold, there are several very effective natural remedies. Lavender essential oil is one of them. It is also useful for removing mold from the walls of your home, both indoors and outdoors.
Baking soda or vinegar is often used to whiten tile joints with natural products. As they are excellent antibacterial and antimicrobial agents, these two quite effective products produce good results. In addition, baking soda also neutralizes odors. On the contrary, vinegar can leave the house with a very pungent odor.
Not just baking soda and vinegar, this other cheap product will do the trick!
In addition to baking soda and vinegar, you can use another product that everyone has at home to whiten tiles. This is hydrogen peroxide, useful for sterilizing wounds.
This product, which is sold in supermarkets for a few euros, is perfect combined with baking soda. They are an effective remedy to eliminate and neutralize moldy odors. Hydrogen peroxide is also an excellent degreasing product.
Simply mix ½ liter of hydrogen peroxide and ½ cup of baking soda (about 100 grams). Mix the 2 ingredients well until you obtain a semi-solid paste.
Using a disposable glove, spread the paste on the blackened joints and rub with a toothbrush or sponge. Leave it on for about 10 minutes and rinse with warm water. If necessary, repeat the operation until the desired surface is completely whitened.
The same process can be used to whiten the joints between bathroom tiles and floor tiles.
Other remedies
Another effective but more expensive remedy is descaling gel for toilets. Simply pour the product between the tiles and let it sit for about 20 minutes. The result is excellent, but it is more aggressive and not very respectful of the environment.
