How do you get rid of mold/mildew in the "white" grout on tiled walls?

Holly Bertone | Pink FortitudeBetsyLynn Sorrell


i have used Clorox bleach pen applied directly to the grout and left it for over an hour but the black colored mold/mildew is still there. any other ideas what i can use to get rid of this. we cannot take out the grout - we need to clean it in place. thanks.

    I've read to use peroxide on grout. I don't have tile so haven't tried it on grout but it worked on the shower surround vinyl trim that butts against the shower.

    Good luck!

    Vinegar kills the spores,Bleach removes the stain it leaves;unless it's under the sealer on the grout then water issues are either under tiles/grout & needs addressed or it will just return;is the grout sealed?

  • Hi Leona - 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
