Hard water causes a build-up of plaque on any surface. The appearance of taps, plumbing, and bathtubs is ruined. Even the indestructible surface of toilets becomes covered with a rusty plaque.
Let's figure out what products will help remove plaque and make the toilet surface sparkle.
Mix 1 teaspoon of salt (soda), heat one glass of white vinegar to 40 degrees and mix both components, treat the surface and leave overnight. The composition will wash away even ingrained stains.
It is enough to dissolve just one package of citric acid in a glass of water, treat a paper towel in it and place it on the problem area for several hours. Then all that remains is to rub the stain with a brush and rinse with water.
You can pour two packets of acid in dry form into the toilet and add it to the tank. Clean the toilet and rinse with water and acid from the tank.
Sweet soda, which contains phosphoric and citric acids, can also cope with this task.
The main thing before cleaning is to remove the leak from the drain tank, which often leads to such formations. Otherwise, cleaning the toilet from red limescale will be useless.
