I will keep this advice in mind the next time I need to derust something. Thank you very much. Bought a house from the 80's from a family of the previous owner, and they left a whole bunch of potentially good tools and other stuff in there.
A badly maintained, clogged, greasy electric chainsaw is on my list of things to open up, clean and lube up as well. Looking forward to that. As a mainly electronics guy, I only very recently started doing simple mechanical repairs. Opened up a fan that had a hard time turning, found out there were no bearings, just a rod acting as the iron core inside a DC motor. Disassembled, applied generous amounts of acetone to relevant parts, dried it up and greased it up. Worked like a charm afterwards, and didn't even lose any screws.
I am sincerely apologetic of posting content that you found not to be dull enough. I will try to be better in the future. Tool restoration indeed is interesting, but I thought merely soaking a tool in deruster for days would be dull enough :(
