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!

    This is so old school. I have been doing these things for years. I don't buy products on the market. So nice to see you doing natural things for a planet. Keep it up.

    Totally agree that XS iron can be an issue with many water sources, particularly well water. Our issue is culture-proven serratia.
