How can I purify mineral oil?
The first was mineral oil will dissolve latex rubber. I was using surgical tubing to pump the oil to the radiator and after a day the tubes had softened and swollen so much they wouldn't stay attached to the pump. That and the oil turned an ugly yellow.
(* the second was warm oil reacts with PVC, and causes the insulation on usb cables to become brittle)
I'm working on the next gen of the project and I'd like to clean up the oil, but I can't quite google my way to a solution.
I have filtered the oil (removed all the bugs) though a coffee filter, and a couple of paint filters, I don't have any reason to believe the rubber is suspended and filterable, but I could be wrong.
Any chemists out there know what I can do?
