I used two gallons of vinegar and the right amounts of salt and lemon juice, I put it in a big plastic tub. I was able to clean quite a bit before it seemed to loose effectiveness. One tip, I'd let the stuff soak for a couple hours, then pull it out and use a cheap paint brush to knock the sludge off. It seems likeit speeds it up a bit?
