Go to any hardware store, or even WalMart, and get a gallon of mineral spirits paint thinner. It's exactly the same thing as Varsol solvent, just with a slightly lower flash point. Another pretty good cleaning solvent for the oil bath air cleaner element is Diesel fuel. It's just slightly more oily than kerosene or mineral spirits, but it leaves a good film of light oil on the fibers in the filter element, perfect for trapping small dust particles.
