Abstract

A method for sanitizing toilets wherein a hypochlorite sanitizing agent and a dye selected from the group consisting of FD & C Blue No. 1 and FD & C No. 3 are dispensed from separate dispensing means into the toilet flush water. The dye is resistant to attack by the hypochlorite and therefore provides an aesthetically pleasing color to the bowl water during the time period between flushes.
