Choose tile cleaning products carefully to avoid damage. Good products won’t damage the tiles.
Mix one cup of white vinegar and one tablespoon of detergent or dish soap into a bucket of warm water.
Add some baking soda to the solution for an extra cleaning boost.
Dip a brush into the solution and scrub the tiles thoroughly, paying extra attention to any particularly dirty or stained areas.
Rinse the area with water to remove any remaining solution.
Use a soft, lint-free cloth to wipe down the tiles and dry them.
Use white vinegar to kill mold/fungus on tiles. Let it sit before cleaning. If the smell bothers you, wipe with water after an hour.
