Restore Your Bathroom Tiles and Grout: Simple Methods for a Sparkling Finish

For grout that remains dull, create a thick paste using two parts baking soda and one part hydrogen peroxide. If the tiles have greasy residue or that slippery bathroom film, add a few drops of mild dish soap. Mix until the paste is creamy enough to stay on the grout lines rather than dripping down the wall or spreading across the floor.
