Watermarks on wall tiles are often caused by long-term moisture deposition, and most of these watermark signs are located in wet places such as toilets and toilets. The method of removing watermark is also very common, and it can be cleaned with household materials.

First of all, let's look at the reasons for the watermark. The main reason why wall tiles leave watermarks is that the waterproof layer is not effective. If the tiles are not completely waterproof, moisture and water vapor will seep out from the wall and fall on the wall and the ground, and accumulate in the long-term shower and water vapor. This forms a watermark on the surface of the tile, which is difficult to remove once it is formed.

Secondly, let's take a look at how to remove the watermark. First, you should prepare some vinegar. Pour a cup of vinegar into the spray bottle, add a few drops of detergent and a proper amount of hot water. Spray the bottled mixture on the wall brick and let it stand for about ten minutes. If the tile is very serious, please soak the mixture in the wall tile and keep it for several hours. Then, you can gently wipe the tiles with a brush or sponge. Finally, you can wash the tile surface with clean water.

In addition, other methods can be tried to remove the watermark on the wall tiles. For example, soda water can neutralize the acidity of vinegar, while bleach can easily remove stains on the surface of wall tiles. But be careful when using these cleaners, don't let them come into contact with your eyes and skin, and rinse them with clear water immediately after use.

In a word, the watermark problem may be caused by the imperfect waterproof technology of ceramic tiles, or insufficient daily maintenance, water vapor accumulation and difficulty in removing stains. Through in-depth understanding of its causes and continuous cleaning, the watermark problem on wall tiles can be solved.
