I've always sworn by Sheldon's spirit in a coke bottle and give it a damn good shake to clean my chains, and now I'm transferring all my old bits onto a new frame, I wondered whether it might work to clean up my frankly filthy old gear mechs. Stick 'em in a lunch box with some parafin, give 'em a damn good shake, then dry them off and lubricate with 3-in-1/wd-40/pro-link chain lube in all the right places. Does this sound like a good idea, or deranged? Am I likely to damage anything? If it does sound sensible, what should I use for the lube? Any thoughts appreciated.
