I have a 1950's oven I use for powder coating that came in handy for the chain. I really want to save the factory chain if I can but it was super stuck from all the years sitting. I have had it soaking in various fluids for several months and the last step was to heat some gear oil and drop in the chain. I got the oil up to about 350f which is the top end of what the oil can tolerate and dropped it in. It bubbled like the pic below for a couple of minutes - I did not expect that...
The chain was very flexible before it was dipped and shows no wear at all, although I was hoping it would have cleaned up a little better.
Hopefully it will hold up!
