I have used it for many years in the shower.
Homemade Grout Mold Stain Remover:
- Hydrogen Peroxide (Regular 3%)
- Baking Soda
Directions:
- 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).
- Apply the paste to the grout area needing attention, and let it sit a 5-10 minutes (or as long as you would like).
- With a tooth brush or small cleaning brush, scrub vigorously in small circular motions.
- 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!

So sorry vinegar is not recommended for ceramic tile. Eventually, it causes pitting.

Vinegar used correctly is actually one of the best choices for ceramic bathroom surfaces. Vinegar however, is not safe for any natural stone like marble, granite or quartz. With that being said, this post is using peroxide and baking soda for grout...if there is anything I can help with or direct you too DIY Cleaner wise, please let me know :) We have dozens of resources on Chemistry Cachet for cleaning.
