Abstract

A cleaning composition, which is self-adhering upon application to a hard surface, is provided. The cleaning composition includes an adhesion promoter, water and a sufficient amount of a basic agent, such that a mixture of the composition with deionized water has a pH of at least about 10. The adhesion promoter typically includes one or more organic compounds, each containing at least one hydrophilic group. The cleaning compositions may also include at least one surfactant selected from the group of: anionic, nonionic, cationic, amphoteric, and/or zwitterionic surfactants; where one or more of the surfactants may serve all or in part as the adhesion promoter.
