PCR 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.
  • Completely removes 3rd degree glazed creosote
  • Eliminates the need for dangerous and potentially destructive cleaning methods
  • Easy to apply and remove
  • Note: Must be applied by a professional
