    Re: Rusty looking stain on vinyl liner

    Is that the wall or floor?

    The two test of satins are:

    1. Place part of a trichlor puck on the stain for a couple of minutes. If the stain starts to lighten then you have organic matter staining it.

    2. Place a Vitamin C tablet on the stain. If that lightens it then it is metals of some sort.

    It is the floor. Thanks Tim!

    I've seen things you can buy that allow you to put a puck or Vit C on the floor and see what happens. Does anyone have any suggestions or recommendations of products that would be helpful here? I think I understand that organic matter would be leaves etc. What about metal, where would that be coming from, if on the bottom, since I think the bottom of a vinyl pool is not metal, so what would that be coming from? Thanks.

    I had a bobby pin once on the bottom for a few days that caused a stain....Vit C got rid of it.
