Just opened the pool and my fiberglass stairs are yellowish. I noticed these stains last season but didn't know the reason. Now I see that it is probably because of iron levels in the water. Since my water is below my steps at the moment, would this be a good time to clean them? If so what cleaner should I use?
Or should I fill up the pool, add a sequestrant, and let that remove the stains? Thanks!
