Quote: What`s a good solvent that actually cleans out here cos the new and UNimproved stuff doesn`t clean and leaves a black oily residual........... Thankxxxx...............
Dominic, I went to a water based solution about 6 months ago, when my solvent based Safety clean parts washer finally gave out. The key is heat. Went with "Ozzy Juice" SW-3 truck grade degreasing solvent ( NAPA store ). Since my cleaning tank isn't heated and heated tanks are upwords of 1K, I went to Walmart and bought a $15 hot plate. Fabed up a mount so that the hot plate sits up against the bottom of my solvent tank. Takes about 15 minutes for my tank ( 5 gallons ) to get up to about 130 degrees. At that temp, cuts grease every bit as good as solvent based stuff. On the down side, once you clean a metal part, it will rust pretty quick if you don't WD-40 it right after it dries. Stuff will even start to strip paint if you leave the part in long enough.
Thankxxxx...............
