grout in shower

10 years ago

After 3 yrs in new shower, I have started to get blackness in random spots in the grout as seen in pics below. Much more visible when wet, when its dry, not nearly as bad. I have an awesome grout cleaner (grout 66) and it wont get rid of it. Is this mold? Any suggestions

Yes, that is mold. Use bleach or other cleaners for mold.

Be sure and leave shower open to air and have a fan blowing into the shower area after showers for a few hours or all day or night will help prevent mold in the future.

Does look like mold,maybe mildew. Buy a Clorox Bleach Pen and "paint" over the cracks. Works for me!

Do you know if the grout was sealed? Bleach or the mold & mildew sprays work good to get rid of the mold/mildew. But for a long term solution, Home Depot sells a 20 yr grout sealer (works wonderful !!) I missed a few spots when I sealed ours & that's where the mildew shows up. No mildew at all where the areas where properly sealed.
