Aqueous-based cleansers for windows, mirrors and reflecting surfaces, free of builder salts and organic solvents consisting essentially of: from 0.1% to 0.5% by weight of a water-soluble, nonionic polyoxyethylene glycol polymer having a molecular weight of between 300,000 and 4,000,000, from 0.1% to 5% by weight of at least one water-soluble, synthetic surface-active compound selected from the group consisting of synthetic anionic surface-active compounds, nonionic surface-active compounds, cationic surface-active compounds, and compatible mixtures thereof, from 0% to 5% by weight of water-soluble, alkaline-reacting compounds, from 0% to 1% by weight of customary auxiliary agents selected from the group consisting of odorants, colorants and preservatives, and the remainder to 100% by weight of demineralized water. The aqueous-based cleansers of the invention dry streak free and give an antifogging effect.
