Manganese ion-derived discolorations are removed from hard surfaces by the use of either dihydroxy maleic acid, dihydroxy tartaric acid, their alkali metal salts, or mixtures thereof. The non-toxicity and non-corrosivity of the disclosed compounds make them particularly suitable for household applications.

A method is disclosed for the agglomeration of chlorocyanurates. The method involves contacting said chlorocyanurates with salts that are non-reactive with it. The chlorocyanurate particles so treated have an increased storage stability and a significantly decreased tendency to segregate when ultimately mixed with a detergent base.

Aqueous solutions containing alkylamido betaines and certain water-soluble inorganic or organic salts provide compositions of remarkably high viscosities. The inorganic salts suitable for this purpose are the sulfates of metals from Groups IA, IIA, IIB, and IIIA of the period table; sulfates of non-metallic ions; and alkali metal carbonates. Organic salts suitable in the present compositions include the citrates, tartrates, succinates, and carboxymethyloxysuccinates of metals from Groups IA, IIA, IIB and IIIA of the period table and the citrates, tartrates, succinates and carboxymethyloxysuccinates of ammonium ions. These salts have a synergistic viscosity-building effect on aqueous compositions containing alkylamido betaines in combination with micelle-forming anionic surfactants. Other salts increase the viscosity of aqueous solutions containing alkylamido betaines only in the presence of anionic surfactants. Suitable inorganic salts in this category include sulfates of metals from Group IB of the period table; alums; alkali metal sesquicarbonates; alkali metal tripolyphosphates and pyrophosphates; salts of halogen acids selected from the group consisting of potassium chloride and ammonium chloride; and alkali metal silicates.

Pourable, stable, liquid, abrasive compositions capable of removing manganese-ion derived discolorations from hard surfaces comprising a solid phase homogeneously dispersed and stabilized within an aqueous liquid phase are disclosed. Said solid phase comprises a water insoluble abrasive material. Said liquid phase comprises a stabilizing mixture, of a tertiary mixture of synthetic anionic surfactant, soap, and a nonionic surfactant, and an electrolyte system, said system comprising a stain removing amount of at least one electrolyte selected from the group consisting of an alkali metal salt of dihydroxy maleic acid, an alkali metal salt of dihydroxy tartaric acid, and mixtures thereof.
