Thanks for everyone's suggestions! I forgot to mention we had already tried the Magic Eraser, and unfortunately it didn't work. I will try the other tips, and see what works best--and will try to remember to post about that. Bleach will be a last resort attempt, since I'm sensitive to that stuff.

I realize it's only a laundry tub. But this happened when it's less than 2 months old, we wondered what it will look like in a year if it's this way now.
