During my last round of fertilizer applications I failed to blow off all of the granules of iron/fert and now I'm left with a nightmare to resolve. At two of jobs, I managed to stain their limestone pool surrounds. Luckily the stains are pretty localized, but they are BAD. I've tried rid-o-rust, lemon juice and a product called Lustro Italiano rust remover. Nothing has worked so far. Does anyone have a tried and true method? And let me go ahead and say I don't need a lecture on blowing off all of the surfaces. As I said earlier, I blew the surfaces, just missed a few spots. Thanks for your help.

I've read on a few different sites that oxalis acid would work, but that it was extremely toxic. I'm assuming they meant the fumes. I think I'm going to try to find some. Did any of you who have used it have to scrub the stain? How long did you allow the product to sit before washing off?
Thanks for the help.

Picked up some absorbing acid today and getting the oxalic tomorrow. If that doesn't work, I guess I'll try vinegar. I'll let everyone know how it/they work. Thanks for all of the responses.
