Creosote Sweeping Log Creosote Remover, 3 lb. is an easy, nontoxic, and cost-effective solution designed to keep your chimney from creosote buildup. This remover works quickly and efficiently, making chimney cleaning simpler than ever. When burned, the chimney sweeping log releases a special mixture of minerals that coat and adhere to the creosote inside your chimney. Over the course of 14 days, this causes the creosote to become brittle and either break away or be carried out with the smoke from subsequent fires. Independent tests have shown that a single use can reduce creosote by up to 70%, while also rendering the remaining creosote virtually non-flammable, significantly lowering the risk of chimney fires.
