Abstract
Disclosed herein are methods of cleaning toilet basins and urinals. Cleaning components are applied to the interior surfaces of these basins other than through the flush water, without scrubbing. They are allowed to be in contact with the surface of the basin for at least one-half hour before normal use of the toilet/urinal. Preferred methods for applying the cleaning compositions are with a spray bottle or an aerosol can, with application occurring on a daily, overnight basis.
