Patent number: 6554007Abstract: An improved composition and method for cleaning and disinfecting a garbage disposal that does not require aerosol propellants or carbon dioxide gas generating reaction systems. The composition comprises a suds stabilizing surfactant and a disinfecting agent, plus other optional ingredients such as additional detergent surfactant and scouring agents. In the method of cleaning and disinfecting, a flow of water is provided to the garbage disposal and the composition is then added while the garbage disposal is turned on. The mechanical action of the garbage disposal grinder blades rapidly mixes the composition with water to create suds and disperse the suds around the entire interior chamber, thus cleansing and disinfecting the garbage disposal. After the suds are generated, the flow of water is discontinued, with the garbage disposal being turned off within about 1 minute after the flow of water is discontinued.Type: GrantFiled: January 25, 2001Date of Patent: April 29, 2003Inventor: William S.
