Standard detergents that are available in the market sometimes contain waxes or polish additives that, wash after wash, deposit glossy glaze on the floor and causes annoying marks. These types of glazes can also settle on some joint grouts. When simply types of foods such as Coke, wine, water, etc.., fall on the floor, they remove this type of glossy glaze and restore the original appearance of the tiles (a more opaque look). In the middle of the shinier floor, the areas without wax appear as opaque marks, but they are actually the only clean parts of the floor. In these cases, the following must be done:

1. First of all, remove the glossy glaze from the entire floor (see table below);
2. Then, for daily cleaning, use neutral detergents that do not contain wax or polishing glaze
