How to clean dark grout

Grout turning white is usually due to efflorescence, which the movement of salt or minerals to the surface of porous material (such as your grout) and forms a whitish coating. Another possibility is that grout containing polymer was used and exposed to too much water before the polymers had a chance to combine.

For light discolouration, dip a toothbrush into a solution of one-part water to one-part bleach and use it to scrub along the grout. Leave for a few minutes and then rinse with water. For heavier staining, make a stiff paste of bicarbonate of soda and distilled white vinegar.

Add Hydrogen Peroxide and Dish Soap

A good ratio is ½ cup baking soda, ¼ cup hydrogen peroxide and one teaspoon dish soap. When you apply your mix, let it sit on the grout for about 10 minutes. This allows the mixture some time to loosen the dirt. Then gently scrub and wipe the surface clean with a damp cloth.

Professional grout cleaners utilize low-pressure, hot steam cleaners to remove discoloring agents from your grout. With the rise in popularity of safe or green home cleaning products over the last few years, many homeowners believe they have their grout cleaning well under control.

Dab some white, non-gel toothpaste onto the grout. Scrub with a toothbrush. When you’re done, rinse a cloth with liquid dish soap and water, and wipe clean.

The most common and effective homemade grout cleaner is a mixture of baking soda, hydrogen peroxide, and dish soap. Cream or tartar and lemon juice is the best all-natural solution for whitening. Avoid using highly-acidic solutions like vinegar because they can corrode grout.

Mix the cleaning solution: Make a grout cleaner paste of two parts baking soda to one part hydrogen peroxide. If you’re working in an area where grout is exposed to grease (like in the kitchen), add in a few drops of dish soap.

Hydrogen peroxide is safe to use on grout, as it is a neutral cleaner that won’t eat away at the grout like vinegar can. Mixed with baking soda, hydrogen peroxide forms oxygenated bleach, and that chemical reaction safely cleans the surface.

Unsealed Grout

Grout that hasn’t been sealed or needs to be resealed should not be cleaned with vinegar. The vinegar penetrates into the spaces for air in the grout and weakens them. Over time, vinegar will deteriorate the condition of the grout by etching or wearing away.

The Tile and Grout Cleaner Results

Baking soda is mildly abrasive so it helps to remove the dirt that is stuck in the porous grout surfaces without causing any damage. Hydrogen peroxide is a natural alternative to bleach that brightens and eliminates germs. Plus it is non-toxic and decomposes into water and oxygen.
