Scale forms not only on the handles and body of the faucet.
Limescale clogs the mesh that is screwed onto the spout. All the water passes through the aerator, so over time the mesh becomes clogged with a thick layer of stone.
The main sign that it is time to remove and clean the aerator is water splashing in all directions.
Water stone is a deposit of solid minerals dissolved in water. The basis is calcium and magnesium salts.
Over time, these components form a real "wall" through which water cannot penetrate. It is impossible to remove limescale with a regular product.
To destroy scale, you need to use an acid-containing agent. Thanks to it, the plaque will fall off in flakes. What cannot be removed on your own can be easily cleaned with a needle or knife.
Household chemicals containing hydrochloric acid are excellent at combating deposits. Vinegar and a solution based on citric acid are also suitable.
