Abstract
Abstract A composition suitable for cleaning glass or glazed ceramic articles is described which comprises, by weight, 0.05% to 0.5% hydrofluroic acid or an acid salt thereof, a second water-soluble acid selected from the group consisting of 0.02% to 4% of acetic acid, hydroxy acetic acid, propionic acid and lactic acid and 0.05% to 0.8% of a non-oxidizing mineral acid other than hydrofluoric acid, 0.01 to 0.5% of a water-soluble anionic or nonionic organic detergent, 0% to 10% of a solvent selected from the group consisting of C 1 -C 4 alkyl ethers of ethylene glycol, C 1 -C 4 alcohols and C 2 -C 4 ketones and the balance water. Such compositions reduce water spots and stains and leave a shiny finish.
