Abstract
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.
Claims15
A method for reducing or removing stains from a plastic or ceramic kitchenware or dishware substrate, or deodorizing or disinfecting said substrate, comprising the steps of:
- a) contacting said substrate with a treating composition comprising a bleaching agent and a solvent which generates heat when exposed to microwave radiation, and
- b) subjecting said substrate to microwaves for a sufficient time to effectively treat said substrate;
- wherein said bleaching agent is a diacyl peroxide.
A product comprising (1) a treating composition comprising a bleaching agent and (2) instructions for-use of the treating composition, said instructions including the steps of:
- a) contacting a plastic or ceramic kitchenware or dishware substrate with said treating composition and a solvent which generates heat when exposed to microwave radiation;
- and
- b) subjecting said substrate to microwaves for a sufficient time to effectively treat said substrate;
- wherein said bleaching agent is a diacyl peroxide.
