Sorry to have been absent.
sagatious: Please accept my apologies. I got pulled away from participation in the Forum just at the time I should have been back peddling. [smilie=1:
I was having a hissy fit and being cranky at my own stupidity about not being more careful with an oil-depleting solution on skin. Years of using methylene chloride as a hand cleaner has resulted in a condition that gives me absolute fits in dry weather. I get those skin cracks on my hands that are both painful and frustrating, and actually openly bleed when aggravated. Hurts like he!!.
Anyway, anyone who is prone to this sort of thing should proceed full steam with this process. Just wear gloves. I received some "left outdoors" range brass that looked like it had been salvaged from the Titanic. I found that a 20 to 30 minute soak rendered them free of the black/gray stains completely.
I dried and tumbled the result and discarded anything that still showed significant copper "liver spots".
I, too, vote for this thread becoming a "Sticky".:drinks:
