Abstract
Methods of using an integrated scraper-sponge having a scraper layer with and edge and fixed between the first and second sponge and/or abrasive layers. The scraper sponge is wetted and applied to a surface that is contaminated. The scraper-sponge is moved about the contaminated surface or dabbed onto the surface. The wet sponge portion loosens residue while the scraper edge scrapes residue from the surface as the scraper is moved about the contaminated surface.
Claims3
A method of using an integrated scraper-sponge comprising:
- a first sponge layer of absorbent material and a second sponge or scrub layer of absorbent material or abrasive material, the first and second layers mated to one another at an interface and being configured and dimensioned to define a sponge body having a first surface being a surface of the first sponge layer and a second surface being a surface of the second sponge or scrub layer, and a continuous side surface around the perimeter;
- and
- a scraper layer fixed between the first and second layers at the interface thereof, wherein the scraper layer includes
- a scraper edge portion protruding outwardly from a section of the continuous side surface of the sponge body,
- a support structure body having an area configured and dimensioned to fit between at least a major portion the interface,
- a plurality of apertures within the area of the support structure body perimeter defining the interface of the first and second layers,
- an interface portion between the scraper edge portion and the support structure body that is within the sponge body, and
- a distal portion having a plurality of openings between an intermediate region and the scraper edge portion;
- the method steps comprising:
- obtaining the scraper-sponge,
- wetting the sponge body,
- applying the sponge body to a contaminated surface to loosen residue,
- engaging the scraper edge portion to the contaminated surface, and
- moving the scraper edge portion about the contaminated surface.
