Re: Chain lube and rust
Side note and sorta related but WD40 works great to get oil or grease out of cement. In what I call my shop and what Carol calls; "I used to be able to get my car in there" if, and I do about 2ce a month, spill oil on the deck. I douse the spot with WD40 (after cleaning up the puddle) and just wipe it. The stuff is amazing at breaking up petroleum based any thing.
First time I tried doing that, permanently scared me from using it on any thing that needs to have metal move against metal.
