[TowerTalk] WD-40

[Patrick Greenlee]

Julio, Don't forget the caveat about not breathing a lot of acetone 
fumes.  Harbor Freight and other outlets sell "acid" brushes, small 
metal handled brushes used with acid flux in plumbing soldering. These 
are good as applicators.  An eye dropper or spoon or whatever depending 
on the specific circumstances can be used.  Mix in ATF with the half a 
can of acetone you have in the previously mentioned glass jar and use 
the jar to soak small parts if need be.

There are plastics that are impervious to acetone and ATF but in general 
I avoid long term contact between acetone and plastics because it is 
difficult to be sure exactly what plastic something is made of. The sure 
fire way to find out which plastic will work is to put acetone in the 
container, seal it up tightly waiting for a good long time to see what 
happens.

Those acid brushes are good for applying No-Alox or thread dope and 
other messy stuff.
