  • Publication number: 20090264330
    Abstract: An aqueous cleaning composition for hard surfaces which is applied to the surface to be cleaned in the form of a foam by means of a spray dispenser comprises a fatty alcohol sulfate and/or a fatty acid sarcosinate, and also isopropanol and butylglycol. The composition can be used in a process for streak-free cleaning of hard surfaces, especially glass. In the course of use as intended for cleaning hard surfaces, the decomposition of the cleaning foam is acoustically perceptible in the form of a crackling noise.
