I recently picked up an old Delta lathe that has decades of pitch, resin, and sawdust caked on it.
I've been trying to clean it with Simple Green and a scouring pad, but it's taking a looooong time. The resin seems to be stuck to the paint better than the paint is stuck to the metal, because if I try scraping it off (with plastic), the paint comes off as well.
Any brilliant suggestions for making this go faster?
