Default home-brew Freon TF substitutes?

I am sure that is true of methylene chloride.

Be careful, though; it is a powerful solvent, removing, among other

things, *all* the oil from your skin, if you have much contact with
it.
It is absorbed through the skin, too, and hurts/burns.

It may also neatly soften or dissolve a lot of the plastics used in

electronics; I don't know.

Methylene chloride is definitely not for electronic components.
It is used a paint stripper. I am sure it would require rinsing
off quickly with another solvent, otherwise your PCB would be
fuggered.
The sadly-missed chloro/fluoro-carbon cleaners would not damage the useful
stuff like plastics, rubber, lacquer, metal, paper et ecetera.


plus they didn't leave condensation- not really sure how they evporated
and took the water with them.

Burns like hell if it gets on your skin, too.

I'd guess that they had a low heat of vaporization... they didn't have
to "steal" much energy per volume in order to evaporate. This would
minimize the degree to which the surface is cooled, and thus reduce
the chance of dropping it to the dew point and causing condensation.

Not all CFCs are equally effective at destroying ozone. Is it possible there
are still cleaners using these "less-effective" Freons?
