[Test-Equipment] Washing electronics

[Rasputin Novgorod]

When working with dirty electronics, or cleanup
after soldering, I'll clean by washing under the
kitchen water tap and perhaps a little dish soap.
(Soldering: start w/ flux remover).

Scrubbing with a toothbrush or surgical hand brushes
helps to free the dirt. Then I rinse thoroughly with 
tap water, then with distilled water, and finally
with Alcohol to quicken the evaporation of water.
Sometimes I'll finish with acetone (or to remove stubborn
things), but there is a real danger that acetone will
remove labels and markings!

I use laboratory squirt bottles (about $5/ea from the 
local University chemistry store) which allow accurate
squirting of liquids with a minimum of waste. The nozzle
is fine enough and accurate enough to give something a
quick spray at the bench, allowing the little bit of
runoff drip onto the floor where it almost immediately
evaporates w/o a mess. They even come with labels.

I also use surgical hand brushes, which are small, disposable, 
very soft brushes used by doctors to cleanup before
surgery. I get mine in Canada for about $1 at Lee Valley.
