I'm too lazy for sanding! lol

I have been putting 'old' parts in a 'vinegar bath', leaving them overnight and the rust just wipes off. There are exceptions of course and it's a longer process than I sometimes want, but vinegar is a very effective rust remover. I do have some naval jelly for the more stubborn areas, but vinegar has yet to fail me so far.

Thanks again for the grease advice and I'm checking out the links for stores. I'm very grateful for all the suggestions.
