I stumbled on the bike chain oil by accident. I was in the bike store and they were out of Tri-Flow. So I bought the chain oil. I didn't like it at all so I set it aside. Then one day I had a really nasty machine and thought hhhhhmmmmm I wonder if the bike chain oil would work on that - it did. I'm hooked. I think it has a detergent in it or something. But it sure does get the rust out of there. I have a machine that was totally rusted up in the nose area - I should get it out and see how it is doing after sitting a couple years. That chain oil is thick. I don't recommend it for every day use.
Well I just dug it out and that machine turns like a champ! The rust is still gone!
