This is my first full season with our vinyl liner pool. I have noticed a scum line on the liner at the water line. I started using a magic eraser and the pool liner print started to rub off (I was pushing too hard). What are a few other ways to maintain the water line? Also, what is the best way to clean the liner track? Thanks!
