ABSTRACT:
The invention is a cleaning solution for degreasing metal articles which contains at least one chlorine-free nonionic surfactant with an HLB in the range of 6.5 to 9.5; a second chlorine-free nonionic surfactant with an HLB in the range of above 9.5 to about 14; a chlorinated nonionic surfactant, and an alkalinizing agent and optionally also one or more of anionic or amphoteric surfactant; hydrotroping agents; solubilizers; organic builders, and corrosion inhibitors. The preferred composition of the invention can replace a vapor degreasing process for cleaning oil, grease, and waxy-type contaminants from metal articles to the level of cleanliness required in the aerospace industry.
