Abstract

This invention relates to demulsifying cleaning preparations having a prolonged surface-wetting effect which contain the following components: (a) builders/complexing agents in an amount of from 0.5 to 10% by weight, (b) one or more alkanolamines in an amount of from 20 to 60% by weight, (c) one or more nonionic surfactants in an amount of from 1 to 15% by weight and (d) water in an amount which, with components (a), (b) and (c), adds up to 100% by weight. The cleaning preparations are suitable for cleaning and degreasing lacquered or non-lacquered vehicle surfaces, engines, floors and walls of workshops at temperatures as low as room temperature with demulsification of the oily or fatty soil removed.
