Poultice Creosote Remover
PCR is a revolutionary product designed to completely remove 3rd degree glazed creosote from flue tiles or stainless steel chimney liners. When PCR is applied, it dissolves the creosote and absorbs it. As it absorbs the creosote and dries, it loses its adhesive properties and falls off the sides of the flue tiles. Any remaining PCR can be easily removed by chimney sweeping. PCR can be applied by brush in areas that are easily accessible or with a specially designed tool that can be pulled up through the chimney by a winch. PCR should be used where glazed creosote is present in order to eliminate the dangers of chimney fires.
