Abstract: The concept is to use a material that is a microwave susceptor as a heat source to provide the energy necessary to instantly turn water into steam. One or more surfaces of susceptor are housed in a steam chamber. When the steam is generated, the pressure built up inside the steam chamber exhausts the steam through an exhaust duct that directs the steam to the cleaning surface. A sponge or other cleaning element is attached to the bottom of the product to allow the user to scrub the cleaning surface.
