Note that "trike" was commonly 1,1,1-trichloroethane, until it got
banned for depleting the ozone layer. That stuff was relatively safe;
indeed, it's safety (non-reactivity) was likely also why it lasted
long enough to reach the ozone layer. Trichloroethylene is more
reactive, more dangerous, and still available.

Hm. I once used three spray cans of trichloroethylene to clean a mimeograph
machine (it hadn't been cleaned since it left Vietnam) and people kept
shutting the closet door. I didn't know about the cancer risk, but it
wouldn't have mattered, we all expected to die young anyway.
I don't suppose a single dose will have any effect. Still, good to know.
Thanks.

I used to love "trike" for de-fluxing solder joints. It worked extremely
well, in small quantities. The stuff that's available now is nowhere
near as effective, and you end up using three or four times as much.
The Institute I worked for as a contractor had a rush of lung cancer
cases in the 90ties.
Seemingly all the workshop technicians that
1: were heavy smokers and
2: used solvents freely to clean experiment
( mechanic, electronic) components

Organic solvents processed via low temp burning are really perfect in that
respect. InstaCancer.
