REFLECTOR: Degreaser recommendation

[Alex Balic]

Hi Hiroo-

There are several types of Freon CFC and non CFC they have varying boiling
points and those with higher boiling points- trichlorotrifluoroethane- were
regularly used in industrial vapor degreasers which I was privy to design-
now with EPA regs most have been converted to aqueous based systems which do
not work as well as the vapor degreasers did- there is another system that
uses something called IPA and cyclohexane, of which I am not familiar, but
it claims to be just as effective and non- ozone depleting.  all Freon
materials have a high affinity for grease and oil and will remove it
entirely- military kind of entirely- you can use R-134A from Autozone- just
make sure that it does not contain an oil charge- you can spray the liquid
onto the soiled part, and the oil will be gone - just as with most things
that are severely effective, you do need to exercise some caution when using
them..

An alternate might be Naptha or TSP both of which will do a great job of
removing oil from your hands for about a day or so if you are not careful

After much digging around.  Another big issue seems to be of just where one
would get ahold of such material.  It looks like it's not something I can
call up some vendor with a credit card number and have shipped to me.
(After reading some more into the nature of the beast, there probably is a
really good reason behind that, too).

 

Any suggestions?  Alternatives?

Alex,

 

Not being really up to speed on my Organic Chemistry.  Is Freon the same
thing as CFC?  There are a bunch of them listed here
http://en.wikipedia.org/wiki/Freon but it looks like PCE
(http://en.wikipedia.org/wiki/Tetrachloroethylene) is what I am looking for.
