Pour it into the bathtub and pour a small amount of water over it. Scale and stains will dissolve immediately
Paradoxically, surfaces that are in regular contact with water and soap get the most dirty. The settling water is rich in mineral compounds. The precipitated scale is most often composed of calcium and magnesium compounds. This type of deposit covers all surfaces and sometimes hardens. Removing it can be a challenge, and classic cleaning products don’t help much. Soap also settles on slippery surfaces and creates unsightly stains. Such a dirty bathtub does not encourage bathing. The bathtub should be thoroughly cleaned at least once a week. Also, after each bath, wash the bathtub and rinse off any residues of cosmetics such as hair conditioners, masks and scrubs. You can use baking soda to remove the deposits. It is an irreplaceable helper in cleaning stony surfaces. Baking soda gently dissolves residual dirt and makes the cleaned surface look like new. Sprinkle the dirty areas in the bathtub generously with baking soda. Add a small amount of water and mix with baking soda. There should be some residue which should be rubbed into the dirt. Wait about 15 minutes and rinse everything thoroughly with running water. Baking soda is safe for the skin and does not cause irritation.
How to clean a bathtub from scale and sediment?
Vinegar is recommended for larger and older stains. Its acid formula is the best at removing scale and dried stains. You can mix vinegar with water in equal proportions and wipe the dirty surfaces of the bathtub with it. In this case, it is worth using it carefully because vinegar may irritate the skin. Citric acid has a similar, but more delicate effect than vinegar. In this case, you can apply it directly to the stone and stains. Citric acid should not be used to clean old stone or heavy dirt. However, it can be a great way to preventively clean the bathtub and prevent limescale build-up.
