  • Cleaning compositions
    Patent number: 4002571
    Abstract: Aqueous cleaning compositions are disclosed as having a minimum film-forming temperature of at least 30.degree. C. and comprising a polymer having a glass transition temperature of at least 35.degree. C. and a metal salt, said composition forming a tacky film after being applied to a soiled substrate. Soil adheres to the tacky film which, as a result of the drying of said composition, fractures to form a removable residue. Soil is removed from the substrate together with the residue. A process which requires no scrubbing is also disclosed for cleaning soiled substrates with said aqueous cleaning compositions.
