Abstract
Cleaning compositions which, as powder or as aqueous formulation based on sodium bicarbonate, sodium chloride and/or sugar, comprise a water-soluble polymeric polycarboxylate as dispersant with the exception of those formulations containing only sodium bicarbonate and polyaspartic acids and/or their salts, to the use of these cleaning compositions for the abrasive cleaning of hard surfaces. A method for cleaning surfaces contaminated with deposits using these cleaning compositions.
