On my shower floor, I seem to get a strange pink build-up over time that I have to constantly scrub away. There are certain areas on the shower floor where water sits after a shower, and those areas seem to have the most pink build-up, so I'm assuming it's something in the water that's left over when the water evaporates.
Has anyone heard of something like this? What is this pink stuff? There are a few spots where I cannot get the pink stuff off no matter how hard I scrub...
(The shower floor/walls are not made of tile, but... eh, some kind of hard plastic? That's my best guess.)
Thanks! Chuck
