Hydrogen peroxide is a powerful cleaning chemical, even when diluted, so only use small dabs of the solution to clean away the stain. It is slightly corrosive, so wash the surface thoroughly with tap water as soon as the stain has disappeared.  If your stain is particularly hard to remove, lay a rag soaked with hydrogen peroxide over the stain. Let it set for 1-2 hours. Then, remove the rag and proceed with scrubbing the stain. Before you use this technique to clean a stain in a visible area, try it out in an inconspicuous spot to make sure it won't damage your tiles. Hydrogen peroxide is particularly effective for cleaning coffee stains, nail polish, and blood stains on ceramic or finished tile. Hydrogen peroxide is a bleach-like chemical, so before you use any other cleaning sprays or solutions in the kitchen, wipe down the tiles thoroughly with water to remove any remnants. Pour a cap of bleach into a 1 gallon (3.8 L) bucket of cold water and mix it. Then, use a white cloth to dab and scrub away the stain. If the solution doesn't prove to be strong enough, add another cap full and try again, but be careful of how much you add as bleach is incredibly bad to get on anything except stains.  Bleach is especially effective with ink, coffee, juice, and blood stains — basically anything that has a hard time being cleaned normally will be wiped away by bleach.  Bleach is infamous for reacting with other cleaning solutions, especially ammonia-based solutions. Be absolutely certain that the bleach has been washed away, and let the area dry for a few hours before you use any other cleaning solutions near the tiles. Wet the stain slightly with water, then sprinkle enough scouring powder onto the floor tile stain to completely cover it. Mix it gently with the water and let the paste sit for a few minutes to react. Then, wipe the stain with an abrasive sponge or a rag.  Scouring powder is effective at cleaning common floor stains such as grease stains, food stains, and water marks. If you need to try another stain removal method, completely dry and clean the area with water first, as some chemicals in the powder could react badly with other cleaners. Borax is a popular agent for cleaning clothes, but it is very effective at cleaning the kitchen too. Mix 1 cup (400 g) of Borax with 1⁄4 cup (59 ml) and dip an abrasive sponge into the solution. Scrub the stained area of tile until it is lifted — this may require some elbow grease for particularly tough stains.  Only use Borax on finished tiles, such as ceramic, porcelain, or marble. Mix 2 tbsp (50 g) of  Borax with 1 gallon (3.8 L) of water to create a solution great for mopping the floor regularly, which can prevent stains in the first place. Simply rub the poultice paste onto the stain to a thickness of about 1⁄4 inch (0.64 cm), cover the area with plastic and let it sit for 1 to 2 days. Wipe away the paste and check the stain to see if it was removed.  Marble tiles have a different structure and makeup to other tiles, and although bleach and hydrogen peroxide generally work, marble poultice is specially made to clean this material. Re-apply the poultice as necessary if the stain wasn't absorbed, and leave it for more than 1 day if the stain is particularly deep-set.
