Many inks contain direct dyes in strong alkali solution. Some may cause yellowing of protein fibers due to alkali in the ink. These inks should be thoroughly pre-spotted prior to cleaning if removal is to be expected. Apply SPOL and work thoroughly into stain. Flush with volatile dry solvent. If stain remains, apply SPOT-BUSTER, flush with steam or water and thoroughly dry. Or lightly feather-dry then apply SSS as a leveling agent and dryclean.
