I wouldn't give her an all out dipping in kerosene spa treatment unless you are preparing to repaint that machine.... Muv's videos have enough fantastic advice to get this one in top working condition. Here is a link - if there is varnish on the bottom leave it - the varnish protects the machine. Simple oiling after cleaning off the herd of cows should get this one going just fine. I'm envious though. I like those little buggers. Anyway look here to find her videos - enjoy
