Wash the walls from top to bottom with a cloth or sponge dampened with detergent. Finally, rinse the surface with clean water and polish dry.
For tough stains, use baking soda. Suitable as a dining room, and a special, cleansing. Small particles quickly remove sticky stains.
If there are few stains, choose soap or dishwashing liquid. Wash the surface with a sponge, after cleaning, wipe the tile dry with a dry cloth.
If there is no soda, take fine salt. It copes well with frozen fat and does not leave streaks.
Follow these guidelines to make the process as easy as possible. In addition, it is important to keep the tiles dry. Therefore, ventilate the premises during or after cleaning.
After laying the tiles, do not save on grouting, choose epoxy, two-component. It is more expensive, but it repels moisture well, which prevents the appearance of bacteria, fungus and mold in the seams. Cement, on the contrary, quickly darkens and absorbs water.
