Grout is the coarse substance that is placed between the tiles when placed on a surface. Grout has a twofold purpose: it fills the spaces between the tiles to help keep together and prevents moisture from seeping into the tiles. The grout that has become black needs to clean. An accumulation of dirt, and possibly even mold, is likely to cause the discolored grout. Cleaning the black grout restores the original beauty of the tiled surface.

Combine ½ Cup of baking soda, 1/3 cup ammonia, ¼ cup white vinegar and seven cups hot water in one bucket. Mix the ingredients with a large spoon.
Transfer part of the solution to a spray bottle. Use a funnel to pour the solution of the cuvette into the spray bottle.
Spray solution over black grout. Wipe with a damp cloth. There is no need to rinse the solution with water.
Mix ½ cup of hydrogen peroxide in a spray bottle with a cup of water for a less expensive cleaning method. Spray solution over black grout. Rub the solution in the grout with a toothbrush. Leave the solution in the grout without rinsing. Peroxide and black spots will naturally dissipate. If there is residue in the grout after the liquid has evaporated, wipe with a dry cloth.
Make an oxygen bleach solution if the black color is still in the grout. Oxygen Whitener is safe to use, even in colored grout. Mix two tablespoons of oxygen bleach for every two cups of water in a bucket. Use a measuring cup or something similar to pour the solution directly onto the black grout. Spread the liquid all over the black grout using a brush. Allow to sit in the grout for at least five minutes and then rub the grout with a toothbrush. Clean excess water and dirt with a clean, dry cloth. Repeat this process if necessary to remove all black stains from grout.
Tips warnings
Never mix bleach or chlorine-containing products with ammonia. The combination can produce fumes that are highly toxic.
