The powerful, yet gentle O-Cedar Scrunge Multi-Use Sponge uses the only patented durable non-scratch scrubbing surface recommended by Teflon quality tested nonstick coatings. Rated the best all-purpose cleaning sponge by Cooks Illustrated after extensive testing in America's Test Kitchen. This dual- sided, odor-resistant sponge has a rippled surface that breaks up and lifts away dirt then rinses clean to prevent stinky and smelly odors. This sponge is safe to use on both cookware and bakeware. After each use, rinse thoroughly and squeeze sponge dry after each use. To further clean sponge, place in the dishwasher. This multi-purpose sponge is designed to be safe on most household, hard surfaces. For delicate surfaces, test first on an inconspicuous area and allow to dry before general use. For best results, replace the sponge every 30-60 days! Built from durable materials, our sponge lasts 20% longer than regular scrubbing sponges. Traditional scrubbers trap and collect dirt which leaves them dirty and smelling gross. The Scrunge is S-shaped to fit perfectly in your hand for comfort and grip!
