For light stains, white vinegar is your must-have ally! It is also very useful if you want to remove limescale from a kettle. First, mix the white vinegar with water in equal amounts in a sprayer. Then, apply the mixture to the surface to be treated and rub with a cloth. If you do not have a sprayer, prepare the mixture in a container and soak the cloth directly into it.
Tip: For head showers, unscrew them and soak them in a vinegar and water solution.
