Abstract

Cleaning compositions, which are typically self-adhering in gel form upon application to a hard surface, and which are desirably capable of being applied in aerosol form, are provided. The aqueous-based cleaning compositions include an adhesion promoter, which typically includes one or more organic molecules, each containing at least one hydrophilic group; and an anionic, nonionic, cationic, amphoteric and/or zwitterionic surfactant; and (c) a propellant. In many embodiments, the aqueous-based composition and propellant are contained within a single compartment of a dispensing device.
