A non-aqueous composition cleaning system and method for a printing press recirculation system. The cleaning system comprises two powdered compositions, each composition being applied individually to the recirculation system in a two-step process. The first composition is prepared by dry blending 15-30% by weight of an alkaline cleaning agent, 15-30% by weight of a detergent salt, 15-30% by weight of an emulsifying/wetting agent, 15-30% by weight of a silicone antifoam and 0-10% by weight of a free-flowing silica additive. The second composition is prepared by dry blending 20-40% by weight of an organic acid and 60-80% by weight of a non-foaming detergent/wetting agent. The method comprises dissolving 10 to 40 grams of the first composition in 45 to 200 milliliters of water for each gallon of fountain solution and pouring the resultant solution into the printing press recirculation system. The resultant mixture is then allowed to recirculate for at least 30 minutes. 5 to 25 grams of the second composition is then dissolved in 40 to 200 milliliters of water for each gallon of fountain solution and the resultant solution poured into the recirculation system. The recirculation system is then run for an additional 10 minutes before being drained, flushed with clean water and the refilled with fresh fountain solution.
A non-aqueous cleaning system for a printing press recirculation system comprising a first composition having quantities of 15-30% by weight of an alkaline cleaning agent, 15-30% by weight of a detergent salt, 15-30% by weight of an emulsifying/wetting agent, 15-30% by weight of an antifoam and 0-10% by weight of a free-flow additive and a second composition having quantities of 20-40% by weight of an organic acid and 60-80% by weight of a non-foaming detergent/wetting agent.
A method of cleaning a printing press recirculation system using a first alkaline composition structured to loosen residue from the recirculation system and a second composition structured to acidify the solution formed by the addition of the first composition to the fountain solution comprising the steps of:
