Clean hard water stains from the tile as soon as you notice them, before they become severe. Combine baking soda with water to make a paste. Coat the spots with the paste then sprinkle vinegar onto it until it begins to bubble and foam. Scrub the paste lightly to remove the softened spots, rinse and wipe dry. Alternatively, use a hard water remover specifically formulated for ceramic tile. Do not use highly abrasive cleaners or scrubbing pads on ceramic tile. Abrasives cause permanent etching on the tile surface.
STEP 5: Adhering Tiles __ If you are using tile, chances are that it's in a setting where moisture is a given__kitchen, bath, entryway and so on. Make sure you use a waterproof adhesive. You can use a premixed adhesive or a mortar, but if you choose the latter, make sure it's a thin_set variety. (Thick_bed mortars require some practice and skill at smoothing to get the tiles to sit flat, and the additional mortar isn't necessary for a watertight finish.)
