Steam Way 301 Spotter Dry Solvent is a volatile citrus-based solvent spotting solution and the key spotter for achieving the removal of gum and most common oil and grease-based spills. It also removes wax and ink without the need for chlorinated solvents.  It is slow evaporating but will evaporate completely following use.  Spotter 301 only takes drops when slowly flushed from the fiber.
