Hello,

I was anxious to see any replies to your post because I have the exact same problem with rust stains from nails in my gunite pool (see post on 8/3 @10:14pm from DonaldVS). Obviously with no replies to your post, I suppose no one out there has any quick fixes to this frustrating problem. I was told that it is almost impossible to get the rust stains off except maybe to use pumice or just cover the stain some how. I tried some vitamin C tabs, but did not see any noticable difference from any chemical reaction. However the rubbing action may have done a little to wear down the surface of the rust. However, the amount of time it took under water to rub the stain may require me to get some scuba gear or a very long snorkel and a weight belt.

Sorry I can't be of more help right now, but I will save this thread and if I find or hear of anything that works I will let you know.

Good luck--

DonaldVS
