RE: Using old Monkote
I got my best results using hardware store solvent, which turned out to be about all methanol. Who knows what the rest of it was.
Problem is, methanol is absorbed directly through the skin and heads straight toward the liver. I did a number on my liver in the early eighties as I was continually getting methanol on my hands. That was a close call.
Ammonia, besides attacking the glue, will also make Monokote haze a milky white after a while.
