Rutland Creosote Remover is a solid granular material used to modify creosote deposits as they form in the chimney. Normally these deposits are sticky, tar-like, unworkable, uncleanable substances; however, this additive sprinkled weekly on the fire helps prevent creosote buildup in chimneys. Catalytic action reduces accumulated deposits and lets fires burn cleaner. Not a substitute for regular thorough chimney cleaning, but it makes that job easier.
