speaking of CFC: Freon TF substitute?

[HiramHackenbacker]

I remember this stuff back in the 1980s. It came in spray cans as contact
cleaner. One crew where I worked had 20-litre drums of it. We used to bath
circuit boards in it. It got rid of dust, oil, water, just about anything.
It could cure intermittent faults even. Technician in a can, some called
it.
But since it is unmerciful to the ozone layer, it was banned in most
nations.
(I have heard there is a thriving blackmarket trade for it though.)
Has anybody found something that works as good as the ole TF?

**Nope. TF was brilliant stuff. I used to buy 5 Litre cans of the stuff.

Weused to bathe ATM card readers in the stuff, it was the only thing
that effectively cleaned finger slime off the feed rollers.
