ABSTRACT:
An article and method for disinfecting a toilet bowl and providing the bowl water with a blue tint or hue, which tint or hue resists oxidation by the disinfecting agent. The article comprises a first product chamber containing a first cleaning composition, said composition including the dye Color Index Dye No. 52,035, and a second product chamber containing a second cleaning composition including a disinfectant agent selected from the group consisting of 1,3-dibromo-5,5-dimethylhydantoin, 1,3-dichloro-5,5-dimethylhydantoin 1-bromo-3-chloro-5,5-dimethylhydantoin, dichloroisocyanuric acid and its sodium and potassium salts, and trichloroisocyanuric acid, the bowl water after the dispensing of the article having an available chlorine concentration of from about 0.1 to about 5.0 ppm, the weight ratio of available chlorine to dye being from about 1:1 to about 20:1. The Color Index Dye No. 52,035 is also resistant to attack by a hypochlorite ion-releasing disinfectant agent, for example, calcium hypochlorite and lithium hypochlorite, in the presence of ammonium ions contained in the water source at a concentration of from 0.05 to 2.5 ppm free ammonia, at the available chlorine and dye concentration stated above and at the stated ratios, and represents a further embodiment of the subject invention. The method comprises the step of codispensing a first solution containing the C.I. Dye No. 52,035 and a second solution of the disinfectant agent, to obtain the aforesaid concentrations and the aforesaid ratio of available chlorine to dye.
