Chosen Solution
My walk-in shower has this nearly impossible black mold that has resisted bleach and abrasives. How do I get rid of it? (Sorry for poor Device choice. Couldn’t find any other item)
I’ve gotten mold on the latex caulking and I used a thick toilet bowl cleaner with bleach. The thick type makes it cling to the area and you need to wait about an hour before washing it off. The one I used is Walmart Great Value toilet bowl cleaner with bleach. It worked great.
Use cleaning vinegar and let it soak. It’s pretty amazing.
