How to Remove Water Spots From Ceramic Tile: As hard water dries on your ceramic tile, it leaves a film or buildup of minerals behind. Harsh cleaners or scouring substances can scratch or scuff ceramic tile, but mild household items can dissolve water spots without damaging the surface. The acid content of vinegar breaks up the alkaline mineral deposits, and the gentle scouring properties of baking soda help remove the water stains and any soap scum to leave your tiles sparkly clean. The longer that water spots remain on your tile, the harder they can become to remove, so tackle them as soon as you notice them.
STEP 7: Cleaning and sealing __ Make sure you sponge off the residue on the surface of the tiles before it has the chance to dry. This step will require several passes over a period of an hour or more. It's a critical stage when you're working with tiles that have a porous or variegated surface. Dried grout can prove almost impossible to remove from indentations.
