    Water Line Stain On Fiber Glass Steps, HELP

    There is a dark stain on inside of my fiber glass steps at the water line. My pool is vinyl lined. What can I use to remove the stain without liner damage. THANKS

    I would try a vitamin C tablet first. Hold it against the stain for 30 seconds and see what happens. If the stain is from iron in the water, vitamin C will clear it right up. If that doesn't work, a Mr Clean Magic Eraser will work on nearly everything else.

    Thanks JasonLine,I'll give the C a shot, if that doesn't work I'll try the Eraser. I'll let you know. Thanks again.

    Hey cleanpool, any results to report? I have a similar dark stain that bleach has absolutely no effect on. I'm willing to try the two suggestions, but just wondered if you had any luck and what your specific resolution was. Thanks for any input.
