The previous owner of my pool used shock to open and close the pool for the 5-6 years before we owned it. There are a couple bleached out spots on my liner, and my ladder has pitting and some rust. Well it had rust. I used a wire cup on my angle grinder and removed the rust and cleaned it up. I contacted SR Smith for part numbers for the plastic pieces and hardware which I will replace before the pool is opened in the spring. Has anybody ever cleaned/polished their ladder? What did you use to do so? I was thinking about getting a grinder/buffer for my garage this Christmas, but that idea has passed. I'm thinking about getting a Mothers Powerball to polish it with. Anybody have any better ideas?
