Not used freon TF for over 25 years I think it was a banned substance.  ours was in spray cans and in bottled form not seen it around buy then never looked.

Can't see any issues with using that..... who needs an ozone layer anyway???

The latest WMO /UN Environment Programme Scientific Assessment of Ozone Depletion, issued in 2018, concluded that the ozone layer on the path of recovery and to potential return of the ozone values over Antarctica to pre-1980 levels by 2060. This is because of the long lifetime of the chemicals in the atmosphere.

But for one aspect that gets better, too many others are already unrepairable.

It was used in spray cans a lot in the electronics biz back in the day. I have an old industrial watch cleaning machine with a Dymo label on one jar marked Freon, and spoke to folks in electronics who would get 20 liter drums of it. It's apparently a lot less dangerous to your health than some other solvents- unless you are smoking around its vapors.

Thanks for all of the responses. 

I was taken aback by the instructions in the manual.

Somewhere around in my lab, I have some freeze spray I used for electronics debugging.  Probably 40 yrs old.  Likely freon, but not certain

Hi  I would most likley think it is. We used it in circuit fault detection along with a heat gun   Archaic I Know.

Years ago the big three auto companies once had huge vats of Freon that they would dip parts in before plating. Long ago I was given a couple of cans of it. It was like magic how well it cleaned.
