Always leave it to act for a whole night or half a day, then rub with the help of the brush and you will start to see results!
Rinse well and that’s it!
Citric acid
In case of more stubborn yellow stains , you can also opt for citric acid .
This element, as well as the previous ones, are used to wash laundry or to make dishes and glasses shine in the dishwasher.
First, take 150 grams of citric acid and dissolve it in 1 liter of hot water. Pour everything into a spray container using a funnel.
NB I remind you that the following remedy cannot be used if you have marble or natural stone ceramics.
Lemon and vinegar
Have you ever tried to remove yellow stains in the toilet with lemon and vinegar ?
All you have to do, similarly to what is described for citric acid, is fill a spray container with white vinegar or wine vinegar and the juice of 2 lemons .
Spray the mixture obtained on the yellow stain and leave it to act overnight. The following morning, spray a little mixture again and scrub with the brush , then rinse.
