The most luxurious toilet renovation can ruin a toilet bowl with yellow smudges.
Such smudges can appear not only due to lack of cleaning, but also due to hard water with chlorine and impurities.
It is useless to try to clean the yellowness from the toilet bowl with citric acid, soda and other means. They can clean plaque, but not rust.
Vinegar
Mix a spoonful of baking soda in a glass of vinegar and apply the solution to the dirty areas.
Pour the sides of the toilet generously and leave overnight.
You can add a drop of iodine to vinegar, but then the solution needs to be slightly warmed up.
Release the water in the morning. Repeat the procedure every few days until the yellow streaks are completely cleared.
Oxalic acid
Pour a small amount of oxalic acid on a rag and rub the toilet well with it. Leave for an hour and drain the water.
If the rust does not wash off the first time, add salt to the acid and rub again.
Oxalic acid is a strong chemical, so you need to work with gloves. If the pipes are plastic, then you can’t clean the toilet with acid.
Electrolyte
You will need electrolyte, which is poured into the car battery.
This method is radical, so you need to resort to it only when other means have not helped.
The walls of the toilet bowl should be rubbed with electrolyte and flushed after 5 minutes. You need to work in a respirator.
Peroxide and ammonia
These penny funds can be bought at any pharmacy.
Mix the products in a ratio of 5: 1 and apply the slurry on the inside of the toilet bowl, rub it, rinse off after 2 hours.
