Hello -
I'm pulling an old machine apart and my usual go-to process is to drop the smaller cast iron parts in a tub of ZEP Industrial Purple. It does a great job at taking all the grease, oil, paint etc. away right to bare cast iron. However, I have a couple of pieces that have Oilite bushings in them. Being Sodium Hydroxide based, I am concerned the ZEP will attack the bronze based Oilite bushings. Can anyone confim/deny this and/or provide me with an alternate technique that's worked well for them?
Side note - after bringing the part to bare cast iron, and then painting etc. again, is there a technique that can be used to "reload" the oilite bushings such as a vacuum chamber or something ? Most of the bushings have gits oilers closeby so it should not be a big issue as they will see a bunch of oil anyway and probably take it up in time, but just thought I'd ask.
Thanks !
