New to me, but I found out why the floor in my fiberglass shower has pink spots.
Supposedly an airborne bacteria that feeds on shower soap and whatever ends up on the wet floor. I used bleach and water and dried with a towel and the pink stains have faded away for now. Anyone else have this wonderful cleaning job to do in their shower also?
Here's a link to the pink stains. Or just search pink shower stains.
