To clean the toilet from yellow stains and limescale, it is not at all necessary to buy expensive household chemicals.
We'll tell you how to bring your toilet into perfect condition using improvised means.
How to clean a toilet
Regular baking soda will help you deal with old stains.
Take a pack of soda (200 g), pour it on the inner surface of the toilet and leave for a while (depending on the degree of contamination). After that, clean with a brush and flush.
Also, 9% acetic acid works well against rust and limescale.
For greater effect, it can be heated to a temperature of 40 degrees.
