PCR is a revolutionary product designed to completely remove 3rd degree glazed creosote from flue tiles or stain-less steel chimney liners. When PCR is applied, it dissolves and absorbs the creosote. As it dries, it loses its adhesiveproperties 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 applicator that can bepulled up through the chimney by a winch. PCR can also be applied with SaverSystems’ Smoke Chamber Sprayer.
