Investigate the location of the stain. This can provide useful information for what caused the stain. Certain cement tile stains will need special cleaning procedures to be removed from the stone. Note the color, size, shape, and pattern of the stain, along with anything in the area that might have caused it.

Cleanse oil based tile stains with a household detergent or ammonia. Some common examples of oil based wood tile stains include grease, tar, or cosmetics. These will cause your bathroom tile to darken. To dissolve oil based mosaic tile stains, clean the area by gently wiping it with a soft cloth and a household detergent, like dish soap, or ammonia. Afterwards, dry the area with a soft towel.

If detergent and ammonia fail to remove the stain, try mineral spirits or acetone. Use these sparingly and as a last resort. Flush these cleaners with water after applying, then dry the area. Eliminate mildew and algae with a heavy-duty cleaner. Mix a diluted cleaning solution containing a half cup (237 ml) of ammonia, bleach, or hydrogen peroxide with a gallon (3.8 L) of water. Clean the surface with the solution with a soft cloth, rinse the area well, then dry it with a soft cloth or towel.

Never mix bleach and ammonia. Doing so will create toxic fumes that can result in serious harm or death. Erase organic marble tile stains with hydrogen peroxide and ammonia. The most common kinds of organic casstle tile stains come from bodily fluids, like urine or feces, tobacco, paper, and food. These may create a brown-pink stain. Clean these areas as you would normally with 12% hydrogen peroxide and a couple of drops of ammonia.

In some cases, you may be able to get rid of an organic stain just by removing its source. After removal, wait a few days to see if the stain disappears. Hydrogen peroxide may fade or lighten the color of your stone. Test it on an out of sight location before you use it. Only use this technique occasionally to prevent color loss.

Use a stone poultice for metal wood tile stains. Mix the poultice according to its directions. Usually this will result in a paste that is the consistency of peanut butter. Wet the stain with distilled water. Apply the paste to the stain so it is roughly ¼ to ½ in (.64 to 1.3 cm) thick. The paste should extend beyond the stain by roughly an inch (2.5 cm). Tape plastic over the poultice, wait the time indicated on the label, then remove it according to its directions.
