Re: 91% Isopropyl Rubbing Alcohol to clean potentiometers?


Gary Robert Bosworth
 

I use Isopropyl alcohol for many cleaning jobs - especially solder flux.
Just don't let it get near a source of ignition. It is almost completely
invisible when lit, and requires a specific type of fire extinguisher to
put it out. The fire can spread very quickly as the liquid is as thin as
water and will run all over the place.

Hi:
Lots of companies sell it. I see it on Amazon for 13.00 U.S. a gallon (4,
1 quart plastic bottles.) It is very hydroscopic (absorbs water from the
air readily)… so unless you store it over a drying agent, it will tend
towards 90%, as it picks up water, from the air that gets into the bottle.
The main advantage of IPA is it is cheap (really cheap compared to
proprietary cleaners, like Deoxit). But, another significant advantage is
that it is a pure (other than the little bit of water)… it is a pure
chemical. So, you know what you are using, and can find out what it will do
to what you are using it on (That part needs some research, or advice.).
You can get (download) the Material Safety Data Sheet (MSDS), so you can
determine how it will affect you, how to use it safely, and how it will
affect the environment. The MSDS for many proprietary cleaners don't
significantly identify what's in them (it's proprietary).
