There are quite a large number of plumbing care products, among which you can choose truly worthy options.
However, many people prefer to use proven natural remedies.
In most cases, they can guarantee a higher degree of efficiency.
This method seems very unusual and interesting, but it gives an excellent result. You will need to take a glass of vinegar and bring it to a temperature of 50 degrees.
Add one spoon of soda to the liquid for greater effect.
Then add a few drops of iodine. Five drops of the drugstore product will be quite enough. Apply the prepared mixture to the surface of the toilet, especially highlighting areas with serious stains.
Then we go over it with a brush or the hard side of a sponge and rinse.
This remedy will easily help to overcome urinary stones and red stains. It is worth noting that the method will not harm the plumbing, so there is no need to worry about it.
