Abstract

Abstract A cleaning composition particularly adapted for the cleaning of hard surfaces, and more particularly for use in car washes for the cleaning and brightening of automotive vehicle surfaces without the use of cleaning implements, such as brushes and buffers. The cleaning composition contains one or more chelating agents including an alkali salt of ethylenediamine tetraacetic acid and one or more surfactants including potassium fluorinated alkyl carboxylate.
