Should You Use “Bleach” to Clean Grout?

While you should never clean “colored grout” with Bleach, you can consider using Chlorine Bleach for “White grout.” 

Chlorine bleach can be used on white grout to remove severe stains, as long as it is diluted with water first.

However, being a harsh caustic chemical, it can cause damage to the grout itself if applied at full strength or if it is allowed to sit too long.

Also, Chlorine bleach can react with other chemicals you may have used earlier to clean your stained grout and produce noxious or dangerous fumes. For these reasons, bleach isn’t recommended for cleaning grout.

If you use Chlorine bleach, wear hand and eye protection, apply with a brush at full strength, have adequate air ventilation, use extreme caution, rinse, and remove all bleach residue with water as quickly as possible.

How Do You Keep Grout From Staining?

If you want to avoid difficult cleaning in the first place, the best thing to do is to keep your grout from staining. Ensuring the grout is sealed correctly is the first step to prevent staining.

Regularly clean the grout using a mild approach like warm water, vinegar, and baking soda. If you keep the grout clean continuously, you won’t have to bring in heavier chemicals to remove accumulated stains.

How Often Do You Reseal Grout?

As stated above, proper sealing is vital to preventing grout from staining. Unfortunately, many homeowners go years or even decades without resealing their grout.

Ideally, you should try to reseal wall grout once a year and floor grout twice a year, and be sure the grout has been thoroughly cleaned and dried before sealing.

What Is the Best Homemade Tile Grout Cleaner?

Among the homemade cleaners, the most powerful option is hydrogen peroxide. As described earlier in this article, white vinegar and baking soda paste are also great home remedies and a highly effective way to remove grout stains.
