Do you often notice yellowish stains or rust in certain corners of your bathtub? This is a warning bell that warns you of the lack of cleaning and the lack of ventilation. To get rid of these yellow stains and limescale deposits, there is a very popular and very effective remedy: the mixture of baking soda and white vinegar. These two natural ingredients are indeed powerful cleaners. Descaler, rust remover, limescale remover, bleach… to take care of your bathtub, you can count on this amazing duo!
Pour a large amount of baking soda over the entire bathtub. Then, use a spray bottle to spray white vinegar on the parts covered with baking soda. You will notice that the two products react to form a white foam, which is completely normal! Leave it on for about 30 minutes. Then use a sponge or soft brush to scrub the dirty areas. Rinse the entire surface with cold water. Don’t forget to open the doors and windows to let it dry naturally. Now clean and shiny, your bathtub can finally breathe!

Ammonia
The biggest problem with shower walls is not dirt, but limescale that builds up over time. To identify limescale deposits, you will notice white or dull spots that do not disappear. This also includes tiles, shower faucets and bathtubs.
