Last update: 18 February, 2020

The grout between tiles is a white compound that deteriorates over time due to moisture, dust and other substances that accumulate on its surface.

However, there are some homemade solutions that you can use as an alternative to conventional products that contain aggressive chemicals that are harmful to your health and the environment. Today, we want to share some of the best methods for effective cleaning that won’t break the bank. Take note!

Cleaning grout

Grout has tiny pores that turn black due to the overgrowth of mold, bacteria and other microorganisms that easily grow in a moist environment. Not only does mold look bad, but it also increases your risk of allergic reactions.

These areas must be cleaned regularly using special products to remove these ugly stains.

Grout cleaning solutions

Baking soda

Clean grout with baking soda.

Baking soda is one of the best products for eco-friendly cleaning of the spaces in your home. According to a study from the American Dental Association, this product can remove the grime that’s stuck on your tiles and it can neutralize harmful bacteria.


  • ½ cup baking soda
  • Hot water
  • 1 brush


  • Combine the baking soda with enough hot water to make a paste and use to clean grout with a brush.
  • Leave for 30 minutes, then wipe clean with a soft cloth.

Hydrogen peroxide

The classic wound disinfectant is excellent for eliminating the mold, dust and other grime that accumulates in the spaces between tiles, according to this study from the Security Mutual Clinical Hospital (Chile).


  • ½ cup hydrogen peroxide
  • 1 brush


  • Spray the hydrogen peroxide on the surfaces you want to clean and scrub with a brush to remove grime.
  • Let work for 20 minutes, then rinse with soap and water.

White vinegar

Clean grout with white vinegar.

White vinegar has so many uses that it was the number one natural cleaner for years.

Its uses around the home are once again beginning to attract attention as an ecologically friendly choice for cleaning your home, according to this study from Harvard University (United States).

Its antifungal, antibacterial, and bleaching properties remove mold from tile and grout, according to a study from Taubate University (Brasil).

It will also neutralize musty smells and leave behind a fresh, clean scent.


  • ½ cup white vinegar
  • ¼ cup warm water
  • 1 spray bottle


  • Combine the white vinegar and warm water and pour it into a spray bottle.
  • Spray the grout and let work for 10 minutes.
  • Scrub with a brush or sponge.
  • If the black stains are really difficult to remove, apply the vinegar directly without diluting.
  • Rinse with warm water and dry with a cloth.

Baking soda and liquid soap

The combination of baking soda, liquid soap and white vinegar gives us an effective solution to fight hard-to-remove stains on grout and tile surfaces.

This solution totally eliminates mold and creates a protective barrier against the fungi that grow in moist environments.


  • ½ cup baking soda
  • 1 teaspoon eco-friendly liquid soap
  • ¼ cup hydrogen peroxide
  • 1 brush

Directions to clean grout

  • Mix the baking soda, liquid soap, and hydrogen peroxide in a bowl.

  • Vigorously scrub with a brush before rinsing.

Bleach water

Clean grout with bleach water.

Chlorine bleach is one of the best products for cleaning, whitening, and disinfecting.

While it’s more chemically aggressive than the other options listed here, it’s one of the best solutions for eliminating mold and grout stains.


  • ½ liter warm water
  • 3 tablespoons bleach
  • 1 brush


  • Dilute the bleach in the warm water and apply to tiles with a sponge or spray bottle.
  • Let work 5 minutes, then scrub with a brush before rinsing.

Apple cider vinegar

While apple cider vinegar is used extensively for culinary and medicinal purposes, it also makes an excellent natural cleaning agent because of its antimicrobial properties, according to this study from the University of Middlesex (UK). Best of all, it’s cheap and natural. Try it and you’ll see how effective it is.


  • ½ cup apple cider vinegar
  • ½ cup water
  • 1 brush


  • Dilute the vinegar in the water and apply to grout using a brush.
  • Let it work for 5 minutes, then wipe clean with a cloth soaked in warm water.
