Due to the high humidity while I was living in Florida, the rods on my Tantillus have pitted. What's the best way to smooth them again. I don't want to ruin my printed bearings by operating it in it's present state.
If you don't fear disassembling them, putting steel into hot (almost or gently cooking) water for a few hours gets rid of any rust. The brown stuff will be replaced by black stuff and can be wiped off. It's a very old recipe for blueing.
