It is important to watch this information if you can because this is really just a simple, natural cleaner. It works great, and there shouldn't be any issue with it. I have used it for many years in the shower.

Homemade Grout Mold Stain Remover:

  • Hydrogen Peroxide (Regular 3%)
  • Baking Soda


  1. There are a few methods for creating the paste. First, add some baking soda into a bowl. Lightly spray peroxide onto the baking soda until a thick paste is formed. Almost like toothpaste (first picture in blog post shows texture).
  2. Apply the paste to the grout area needing attention, and let it sit a 5-10 minutes (or as long as you would like).
  3. With a tooth brush or small cleaning brush, scrub vigorously in small circular motions.
  4. Rinse

Also, if you are worried about residue, just spray some rubbing alcohol on the solution after rinsing or use hot soap and water. There shouldn't be any issue with residue!

With the thick consistency, applying to grout is easy. I just rub it on like shown above!

    Toilet bowl cleaner with bleach works great. Still needs scrubbing to get out stubborn stains or marks. Yes, knee pads do help with this project. Unfortunately, this product or an actual grout cleaner did not work on my shower floor smaller tiles.
