In reply to lost1977: Theres an old roadie motif that rings true, a clean bike is a happy bike... thus a clean chain is a happy chain. Usually wd40 and a dry cloth will help remove the grit and dirt if you dont have a chain bath device thing and then some proper chain lub applied whilst turning the cranks, allegedly the trick is to oil into the middle of the chain from above and not just coat everything.. then leave it for a few seconds and remove excess oil. Excess oil will pick up more dirt and grit and compound the problem. Job done.
