How do I get black mold out of the grout in my shower?

A paste of vinegar and baking soda.

And a respirator. You do not want to breath black mold.

I use Tilex with Clorox bleach...the best!

Are you sure it's in the grout or is it in the caulk? If it's caulk, sometimes, you can't get it out. Then you have to scrape it all out and put new back in. Be sure to follow directions and get mold and mildew resistant caulk.

Hi Margot - There are several ways to get rid of mold, but most importantly, you need to address the root cause to keep it from returning. This article focuses on the bathroom, but is an overall great article that covers methods of how to remove mold, if bleach is safe to use, and how to prevent it from coming back. Hope this helps! Hugs, Holly
