Hi peeps,

looking through this lovely forum was trying to find what might be staining my pool liner at the water surface and what i might use to best remove this.
The stain is "dirty" brownish - the liner is cream in colour, so "dirt" quite obvious. My guess is that this is organic in nature rather than any type of metal stain. Not sure if I could get metal staining as have no steps etc, but realise that this may be coming from metal salts in the water...

neither chlorine nor "specialist" liner cleaners seem to do the trick.

I have seen the Vitamin C test - Is this what I should be trying first on the stain? Or is there some other way of removing this stain? I realise that the ascorbic acid clean would require me to fill the pool up higher than the tide mark, so that it's covered - is that right?

there are no marking anywhere else in the pool except the skimmer area, where the basket goes and that's very much darkgreen/black.

Anyway, I may have this all wrong - so any pointers would be much appreciated.

thanks.

Woodyp's suggestion of the magic eraser is a great one. My wife keeps some at the poolside, uses them frequently, works great! Good suggestion.

Will get some erasers just as soon as I can. Don't have them in France, so will have to wait until I go back to the UK. Thanks for the suggestions guys and gals.

I seem to be repeating myself a few years later. The magic sponge has worked a treat up to now, but this year I have been unable to remove the stains. Has my liner finally had it??
