Abstract
A method for sanitizing flush toilets wherein a sanitizing agent and a triphenylmethane dyestuff are dispensed separately from a dual dispensing means into the toilet flush water. The dyestuff is resistant to attack by the sanitizing agent and therefore provides an aesthetically pleasing color to the water remaining in the bowl during the time period between flushes.
