Patent number: 6306219Abstract: The present invention is in the field of liquid or gel detergents. More specifically, the invention relates to a method for removing stains and/or odors and for disinfecting plastics, and other substrates by applying a liquid or gel detergent composition to the substrate and subjecting the substrate to microwaves. This method provides enhanced cleaning and improved stain removal on plastics, and other substrates. These cleaning compositions include a bleaching agent, preferably diacyl peroxide in a liquid or gel detergent formulation. These compositions in combination with the method of microwaving are also very effective in disinfecting and deodorizing substrates.Type: GrantFiled: January 25, 1999Date of Patent: October 23, 2001Assignee: The Procter & Gamble CompanyInventors: Kofi Ofosu-Asante, Howard David Hutton
