Martin/F. Weber Turpenoid is an odorless, very volatile, thin, colorless, turpentine substitute. Turpenoid has the same painting properties and drying time as turpentine but is free from the strong characteristic turpentine odor. Compatible with oil colors as a painting vehicle, either alone or in mediums. Turpenoid is also excellent as a solvent or paint brush cleaner, and for use in removing paint spots from clothing.
