I love the spray on chain lubes available at the auto parts stores. Chain starts sounding dry and crunchy, spray on some lube. I wipe it down with a paper towel to get the slobber off. Chain now quiet and away I go. Once in a while I am forced to scrape off all the accumulated goo on derailluer pulleys. Wipe or scrape off accumulations of goo on sprockets and frame but that is only once in a while. Ride Ride Ride. Chain gets noisy spray some more chain lube on. My chains last for years and yes I do check them for wear. Lets go Riding some more, chains are quiet right now.
