Why do the seams between the tiles darken? The seams between the tiles gradually darken and have to be washed.
The gaps between the tiles are filled with grout or other construction materials. They are highly resistant, but can darken under the influence of moisture and splashes of water and grease. High humidity promotes the growth of bacteria, fungi and mold in the joints, which leads to a change in color. They not only spoil the appearance of the walls, but also harm human health. Therefore, if darkening occurs, the joints should be cleaned, disinfected and dirt removed.
