Our pool is two years old and the fiberglass steps have a black ring around the water line. The steps are also not bright white anymore, just kind of dull and I would like to restore them to white. Does anyone have suggestions on how to clean them. I tried the Mr Clean Eraser last year with some success on the water stain but it still did not cut through all of it. The steps are underwater and I can't drain the pool to clean them. Any help is appreciated.
Also, this is my first post and I would like to say a big thanks for this forum. We were novices when we built the pool and have learned so much from this forum, especially pool school and the pool calculator. I have found almost all of my questions answered here.
