摘要： A concentrated detergent formulation effective to remove grease includes a glycol ether solvent system in combination with a high concentration of a surfactant system stably dispersed in water. The surfactant system is preferably a combination of a hydrotrope and a nonionic surfactant with a concentration preferably in the range of 7 % or greater. The glycol ether solvent system can be any of a number of glycol ethers with dipropylene glycol n-butyl ether and dipropylene glycol monomethyl ether preferred. The formulation can be used at high concentrations to effectively remove baked-on grease in deep fryers and clean parking lots and can be used at a lower concentration as a presoak and even at a more dilute concentration for general purpose degreasing and spray and wipe cleaner. The product is low alkaline and non-corrosive.
