Hey all
About 9 months ago my son threw a 9V battery into the pool. I didn't notice it for a day, and by then it had left a couple of nasty stains on the pebble quartz. I tried scrubbing, I tried chlorine pucks, nothing worked.
Then, today, 9 months later, I tried the Vitamin C trick, and WOW - they are almost unnoticeable!
