I did a search but could not find an answer.
I have a vinyl liner and have a stain from a pine cone that was sitting there (my solar blanket was on when I went away for a few days).
How do I get rid of them? They are in the deep end, of course.
Second type of stain.... in a couple of spots a screw driver bit fell in and left stains in a couple of spots. The stains are sort of yellowish-brown. In the shallow end.
I might try one of those Mr Clean magic erasers, which do wonders.
