I'm curious about the proper cleaning of electrical terminals on our MJs. They seem to really gunk up, sludge up, and tar up quite heavily over time. Here in Alaska, a can of electrical parts cleaner costs around 7 bucks, which is far too much to blow through them regularly. So I'm curious if you can use a kerosene pumping parts cleaner to soak/clean out the electricals, then spray off the consequential residue with the electrical parts cleaner. Anyone know if it's safe for the electricals?
