All this is so amusing.
Elemental mercury isn't all that dangerous, its the salts that are.
And I played with a bunch of it in my teen years. Just think how smart I'd be today if the stuff hadn't retarded me!! I went for a long time with mercury smeared silver coins.
Back during my rocks and mineral days, one of Dad's hobbies was working on jewelry. He'd occasionally resize a ring for someone or have a small amount of gold filings on his workbench. All the "fines" went into a jar. Same with our experiments on gold panning. We often would get some color (not enough to make us rich.) All went into the same jar. Then dad just poured our stockpile of liquid mercury into the jar. It went out in the yard for a cookout kind of thing. No food involved, just a nice hot charcoal fire and a still made from some copper tubing (where we got it I haven't a clue. The still part didn't work all that well, the mercury tended to condense on the inside and only a small part was recoverable. Guess my childhood home is now a brownfield. Anyway, what we got out was a fair amount of "paydirt", all still coated with a crust of some mercuric compound. Dad sold it to someone.
A few years ago my buddy Doug asked if I wanted any mercury. I said no, because by then it was being treated like nuclear waste. He had a flask ( I think that's some kind of measure, like 76# or something.) He got it out of some measuring instrument from the distant past.
I've still got some in the basement. Its in 2 or 3 thermostat switches. Chances are you've got some too if you've got an older house. Take the cover off your thermostat. Look to see if you've got a glass vial with wires running from it, like a light bulb that doesn't light up.
Back to cleaning guns.... Its a good way to remove lead. We've all agreed on that. The problem is first recovering the remaining liquid part.
Then you've got to figure out how to brush the amalgam that appears to be a dry, crust material. Its easy to brush out. If you use a stainless brush, it won't even cling to it. But the dust will be everywhere. If you decide to try the trick, do it outside, away from the house. Wear a mask. Then don't tell anyone what you've been up to. Oh, dispose of the clothes. All just on the outside chance the EPA is right (there might be a first time.)
Now can we discuss the DDT Dad used to keep in the garage?
