I have a pretty nice mountain bike that I took out for a ride in the winter while there was snow on the ground. Unfortunately when I was on my way back the salt truck came around and now I find myself with a rusty chain, chain rings, and a bit on the screw where the pedal enters the crank. I couldn't clean it because it was well below freezing and the stuff would freeze before i could get it back in the garage. Any advice would be much appreciated! ~~Thanks
