Salt is said to fight Creosote.
Spreading a Cup or so of Table Salt or Rock Salt on a bed of red-hot Coals every few days has been reported to dry out Creosote deposits, causing them to flake off, drop down, and be harmlessly consumed by the fire. How often this treatment is needed would depend on how dry your FireWood is and how hot you maintain your Wood Fire.
