For cleaning Airmite or airbrush or for removing Hilite, Shadow, or Lithco Color (if necessary). This solvent will also dissolve Stoneweld IF USED BEFORE IT HAS HARDENED. Lithco Solvent is the thinner for Lithco Colors if any thinning is needed for spraying. hilite and Shadow require no thinning for perfect spraying. NOTE: This is the only solvent, except some highly flammable, which will keep the Airmite airbrush in tip-top condition. Flush after each use and the Airmite will always be ready for use. The easy way is to place the Airmite (after use) in a closed vessel containing Lithco Solvent. Have enough solvent in vessel to cover nozzle and material tube only. If this is done, no flushing is necessary. Gasoline or naphtha are of no value for cleaning the Airmite, as they do not dissolve Hilite or Shadow.
