I'm a Chemist at an environmental lab, you guys using TCE, carbon tetrachloride, diesel or gasoline are just making my job more stable, thank you. :thumbup:
(gasoline works really well.)
I've no trouble using an "environmentally friendly" (EF) solvent to clean things -
if the damned solvent works somewhere near as well as what it's replacing!
TCE isn't in brake parts cleaner anymore - it's mostly MeOH, from what I've seen. I have to use 3-4 times as much MeOH as I did trich - where's the benefit?
Starting fluid was diethyl ether - now it's mostly heptane. Problem is, I used to use it as a cleaner as well - and I didn't need much of it at all. Heptane doesn't work as well.
One of the few EF cleaners I like is LPS PrecisionClean - it works well, I don't need a lot of it to do a job, and it works on nearly anything. But, I can't find it anywhere anymore (JFTR, most LPS solvents are quite good. They
get it - it's not about profiting from protecting the environment. If I have to spend a little more to get an EF solvent, that's fine - but I'm not going to spend a little more per unit when I have to use anywhere between three and ten times as many units as I did of the stuff I used before. May be environmentally friendly, but I'm not rich enough to play that game.)
I used to clean competition rifle brass in carbon tet. Had a quart can that lasted me something like 10-12
years, and my cousin is probably still using the same can. You drop the brass in, leave it overnight, pull it out, and let it dry. Throw it in the tumbler to get rid of any remaining deposits - they're loose, they just didn't fall out.
That would get be better-looking brass than if I'd left it in the tumbler running for a straight fortnight.
