The Carpet Shark is the ultimate spotting tool. With a serrated scraper, spatula blade, and a penetrator/groomer, the Carpet Shark gives you everything you need to attack gum, tar, adhesives, and more. Use the penetrator teeth to perforate gum deposits. This makes penetration of solvents more effective. Use the serrated scraper teeth to break up crusty stains without damaging fibers. Use the groomer teeth to lift and separate fibers during stain removal procedures and use the spatula blade for normal “bone scraper” applications.
