Steve, 
I have used conformal coat thinner that is about 80% MEK. It does an
excellent job of cleaning TakPak, Loctite 3621, 3609, 3607 and other
epoxies. Try that first.

Subject: [TN] Solvent for cured cyanoacrylate adhesive

Mornin' all,
 
I have a question for the chemists out there about the solvent used to
clean-up cured cyanoacrylate adhesives. Loctite sells a solvent called
768 X-NMS Solvent that works pretty well, but it is expensive. Anywhere
from $20.00 to $37.00 for a little 1.75 ounce bottle depending on where
you buy it.
 
I do know that it is composed mainly of nitromethane with a little bit
of toluene according to the MSDS. My question is; I can get a gallon of
nitromethane at a high-performance auto parts store store nearby for
$50.00 a gallon, would pure nitromethane do the job? Or do I need to add
the toluene as well? 
 
The MSDS gives a range of percentages of both components, but is kind of
vague:

I'm just trying to save a little money is all...
 
Steve
