Abstract
The scrubbing or scouring pad of the invention is an artificial sponge made from a foam material that changes firmness or rigidity based on the temperature thereof. The foam sponge is then covered with a plastic mesh to increase the scouring power thereof. If desired, the foam may also include thermochromic additives therein that change the color of the foam based on the temperature. This provides a visual indication of the temperature of the foam.
