Ashtrol
Protect your furnace from the inside out with Ashtrol, a firebox pH modifier designed to reduce corrosion. Simply add a small scoop with each load of wood to help neutralize the acidic nature of ash. Left untreated, ash buildup can rapidly eat away at your firebox, shortening the life of your furnace.

For complete protection, pair Ashtrol with MolyArmor 350 Corrosion Inhibitor (p/n 2900630), which safeguards the water side of your system. Together, these basic maintenance items play a critical role in extending the life and efficiency of your furnace.
