I do not leave the Finish Line on the machine since it is rather heavy. I clean it off and use a light weight oil. If you do not have a bicycle shop near you to buy Finish Line Wet, you might try cleaning with automatic transmission fluid since it should have a detergent effect, too. Be sure to clean up as you go and use a light oil once you are ready to sew with it. A lot of repair info as well as knowledgeable people have moved to the victoeiun Sweet Shop - see SteveH for a link and correct spelling
