Anonymous users2024-01-23There are two main types of yellow dirt, one is metal (mainly iron) rust, and the other is urine alkali; There are two main reasons for this, one is that it is not flushed and cleaned in time after use, and the other is that the glaze layer of porcelain tiles is not acid-resistant. Solution: First, flush and clean in time after use to keep it dry; The second is to use less acidic detergents and less hard tools to scrub, because the acidic substances not only cannot be restored after corroding the glaze, but the surface is also prone to pits, and it is easier to form dirt; Hard tools are also prone to scratching surfaces.
The best way to do this is to flush it with water, using the same kind of plastic "toilet brush" that you can find in stores.
