I make my own vitriol at home out of old coffee grounds, motor oil, gasoline, and Windex and it works better than any commercial stuff. It'll clean BP, leading, corrosive salts, and even refinish my Mosin stocks.
Add a little diesel fuel and some salt and pepper with that and you can use it as a bear repellant also!
I laughed so hard reading this thread that it's given me a headache.
