Vinyl liner stain, above waterline

[ckelly]

Well, I tried the magic eraser. Not much luck, with A LOT of scrubbing, some of it came off, as did some of the liner print

I also tried the vitamin c, without the sock, but just crushed some tables and sorta rubbed it on the stain, didn't seem to do anything either.

Any more ideas? Can I use some form of cleaning agent or perhaps even a diluted muratic acid to disolve or loosen the organic stain? Not sure how the acid will treat the liner, but I know it works great in plumbing, cleaning showers, etc. without harming plastic. I tried simple green too, no luck.

Is the sequestering agent a pool store product, or is there some other sources for it? What kind of maintenance program do I need to follow with it. As if I can't detect the suspended copper, how do I know when to treat again?

Thanks so much,
Clay

Too bad that niether worked. I f the vitamin C didn't work, then I am thinking it is an organic stain. I don't know about the diluted acid on a vinyl liner. I don't have a vinyl liner pool. Have you tried some diluted bleach? Maybe spraying some on the stain, then using a small scrub brush would work ,it should if it is organic. If when the level of the water was raised, it took off the ring, then I would think bleach would work. I know that there are pool cleaners that break down enzymes, like body oils and such, but I have not used them either. Maybe some others can say what they use.

As for the sequestering agent - you can buy it at any pool store. The directions are on the back, and it tells you what you need for a maintanence dose. You will be able to tell if you are using enough when you have no more "green hair". I would also read the trichclor puck container and see if they are the source of copper. Last year when I was buying them, I had a heck of a time finding the pucks without the copper - it seems a lot of companies put copper in them to act as an algacide., Too bad it only causes problems.

I am using "shaklee's" "liquid at ease" cleaner right now and it seems to be working...active ingredient...calcium carbonate....
