Abstract

This invention relates to an aqueous solution of an alkaline degreasing agent employed for cleaning of metal products surface, and an alkaline degreasing agent employed for making up and replenishing the alkaline degreasing solution. The essential consituent for these alkaline degreasing solution and agent is a compound, such as an alkyl dimethylamine oxide, a nonionic surface active agent, whose structural formula can be described as follows; ##STR1## wherein R is an aliphatic hydrocarbon group having the number of carbon atoms 12-22. The present alkaline degreasing solution can improve degreasing effects without lowering its deforming performance even at a low temperature.
