Meeco's Red Devil Stick Soot-Shot Soot Remover, 3 oz. is a powerful toss-in soot remover designed to improve heating efficiency by oxidizing and eliminating soot build-up in chimneys and flues. This product helps prevent the potential ignition of soot, which consists of unburned carbonaceous particles that cling to combustion chamber walls and the inside of flue and chimney passages. Over time, soot can accumulate enough to obstruct the normal passage of flue gases and even cause dangerous chimney fires. Easy to use, simply toss the stick into an active fire to keep your wood stove or fireplace running safely and efficiently. This 3 oz. soot remover is an essential maintenance product for anyone using wood-burning heating appliances.
