Re: [DCHAS-L] spontaneous combustion of methyl soyate
Nothing was better than the nice petroleum distillates. If the process is to avoid VOCs, mineral oil is not volatile. It works for me. We are suggesting cleaning metal etching plates with baby oil followed by plain old soap and water. Works like a charm. And now the rags can go anywhere without fear of spontaneous combustion.
But you need something that can really chew off the schmutz. And the soyates will do that. So I'm not much help here.

Sorry if I wasn't clear. I got out of printing 10 years ago when the getting' was good. This new product I'm working on is an immersion cleaner in a totally
different industry (automotive aftermarket). End users will be instructed to dunk their part-say a carburetor-let it soak for an hour or two, and then rinse/spray it off upon removal. There shouldn't be any oily rags.
Shouldn't. But never say "never."

Well, that's all well and good from a safety point of view, but not from a printingmaking point of view. You want oils that are unsaturated and will spontaneously
combust since you want the reaction that causes that combusting to occur slowly in the ink when it is printed out on paper or textile so it will dry and set up. The heat of the reaction is easily dissipated on the flat paper or textile. Otherwise you have
an unset ink the smears and for a long time, perhaps forever.
You just have to teach them about the reaction and how to handle these rags
