Superkleen Spiff is the best cleaning fluid to go into cleaning guns. It completely removes cured plastisol inks, most water-based inks, flock lettering and adhesives from all textiles. Its unique oxygenated formula leaves fabric free of any trace of the ink smudge. Unlike other cured ink removers, S.P.I.F. is a full-strength product and does not contain any petroleum hydrocarbon "fillers." This ensures that the ink marks are removed using a minimum of product.
