Mold, mildew and soap scum can ruin the appearance of your shower tile and make an otherwise clean bathroom look grimy and unkempt. The biggest problem with cleaning shower tiles is the growth of mold and mildew in the porous cement grout between each tile. Removing stains from the grout can be a difficult task, but once clean, it is not difficult to maintain the tiles and keep them looking like new.
Spray the entire shower surface with a commercial tub and tile cleaner, and allow it to sit for 15 minutes so that it has an opportunity to penetrate the soap scum, mold and mildew on the shower tiles and grout.
Scrub the shower tiles with a scrub brush or toothbrush--paying particular attention to the grout between the tiles.
Rinse the shower tiles thoroughly with water, and reapply the cleaner as necessary to stubborn mold and mildew stains.
Dry the tiles thoroughly with a squeegee or dry absorbent cloths so that no moisture remains on the shower tiles or grout.
