A pourable, storage-stable manual dishwashing detergent is provided. The detergent contains at least 45 percent sodium bicarbonate with a mean particle diameter of at least 150 micrometers. The sodium bicarbonate is combined with an anionic surfactant, an alkyl polyglycoside surfactant, a zwitterionic surfactant an electrolyte and optionally a solvent, to form the detergent. The detergent of the invention has good pouring properties and excellent cleaning performance against dried-on and burnt-on soil.
