The Best Value For Carpet,Tile & Air Duct Cleaning!
Tile floors or countertops often show their age over time. Usually this is not a result of the tile itself becoming worn, but the grout in between the tile. Many people opt to whiten the grout, but you also can darken in between the tile with grout stain. Coloring the grout will hide dirt that won’t come out, and grout stains come in different colors to complement your tiles. Darkening grout is an inexpensive way to alter the look of your tiles without replacing them. Follow these easy instructions for darkening grout.
Clean the tiles and grout. Pour liquid dish soap onto a damp sponge. Gently scrub the surface of the grout lines to remove any dirt or dust that has not absorbed into the grout. Rinse with a clean, damp sponge. Allow the grout to dry for at least 3 hours, or until it is completely dry to the touch. Grout stain will not adhere well if the grout is damp.
