Abstract
The invention discloses cleaning compositions which employ a synergistic combination of a ester solvent, preferably a fatty acid methyl ester in combination with one or more linear alkyl amines. The alkyl amines act as to remove and suspend organic oils which have been burnt or adhered to a surface with heat and may even be used alone as a soil removal agent. The cleaning compositions have particular use in cleaning of distillation towers associated with biofuel, and vegetable oil refining, but also find use in cleaning ovens, food cooking surfaces and even dry cleaning.
