I tried searching but my search fu is weak today. I am pretty sure it's been discussed here before but I can't find it.

Anyway, I took out my broad sword last week for the first time in 5 or 6 months and noticed it is starting to get a couple of rust spots on the one side. What is the recommended method in removing this? Can I use steel wool and some oil? If so, what kind of oil should I use?
