I was told about this by a guy who races dirt bikes. I've tried it and it works great.
Scott's Liquid Gold, a wood cleaner and preserative sold everywhere, cleans and lubricates the chain. It has a solvent base for cleaning and a light oil ingrediant. It comes in either aerosol or pourable. You can spray it on or remove the chain and soak it in the Scott's product. Give it a try; your wife probably has a can with her cleaning supplies or Wally World, the supermarket, Ace Hardware, the stuff is easily available. One 14oz can will last you forever; well, at least through the riding season.
