I do have a few gallons of Phosphoric acid that I pick up a couple of year ago at one of the big box stores. I haven't tried using it yet, I'm not a chemist and when I see the word acid on somthing it scares the bajebers out of me. I'd use it in fact I've got a couple of kits from Caswell that I'd like to try. The only hang up I have is what to do with it after I'm done with it. Never found anyone that could give me a straight answer on that one.
