Abstract
The invention provides an improved, liquid aqueous hard surface cleaner containing a fluoropolymer having a molecular weight of no less than 5,000, further containing preferably a nonionic surfactant, optionally, a quaternary ammonium compound, a chelating agent/buffer and water to provide enhanced cleaning of hard surfaces, especially vitreous surfaces, in which the thus cleaned surface is rendered soil and stain repellent.
