Abstract
A method of eliminating or at least reducing toilet odor by applying a liquid composition directly to the water contained in a toilet bowl prior to use. The liquid composition contains about 60 to about 70 weight percent diethylene glycol monoethyl ether (CH2OHCH2OCH2CH2OC2H5), the balance being at least additional constituent, such as fragrances and/or stabilizers. The liquid composition reacts with the water so as to roil in the water, forms a sheen on the surface of the water, and reduces toilet odors during and following usage of the toilet bowl.
