For the past 1000 miles I have only wiped down my chain and cogs with a dry rag to get the gunk off, and then occasionally add chain lube (some generic brand of white lightning). The rag gets filthy after a use, I try to just clean it in a sink/shower as I don't want to throw it in a washing machine. How do you guys clean the rags you use to clean bikes?
Also, how important is it to add degreaser before wiping down the chain and gears? Will I notice a big improvement in shifting or will the chain stay cleaner? I'm not talking about buying one of those park tool chain cleaners, just getting some type of degreaser.
