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

A method of treating a flush toilet which comprises a flush tank and bowl, with a sanitizing agent each time the toilet is flushed, and providing a persistent color to the bowl water between flushes, said method comprising the step of dispensing into the flush water an aqueous solution which contains (A) a sanitizing agent having oxidizing characteristics, and (B) a triphenylmethane dyestuff selected from the group having the formula ##STR10## in which:
- R represents benzyl substituted in the benzene ring by SO.sub.3 M in which M represents an alkali metal cation, an ammonium ion or an alkaline earth metal cation;
- R.sup.1 represents a non-tertiary C.sub.1 to C.sub.4 alkyl;
- and
- X represents hydrogen or hydroxy.
