If there is cement adhesion on the surface after solidification, it can be cleaned with toilet cleaner and steel brush. After cleaning, it can be washed twice with clear water, so that the toilet cleaner can be thoroughly cleaned to avoid the corrosion of the ceramic tile surface.

In addition, in the process of paving, there is cement or sand on the surface of ceramic tile, so it is suggested to clean it with clean towel and water in time to avoid the situation that the concave-convex layer on the surface of ceramic tile is difficult to clean after cement solidification. The hardness of sand grains is higher than that of ceramic tiles, and it is easy to cause scratches on the surface of ceramic tiles after rubbing.

If the washed and dried tiles are still white, you can buy edible white vinegar and apply it evenly on the surface of the tiles. After ventilation and drying, the white phenomenon can be eliminated.
