A buildup of creosote is the main reason that it’s important to have your chimney cleaned and inspected annually. Tar, soot, and creosote are all byproducts of wood burning. What’s needed to properly clean your chimney depends upon what level of creosote there is on the flue lining. Creosote in all of its forms is dangerous, as it can cause deadly and destructive chimney fires.

The Birth of a Headache

Third degree creosote is a tough problem to deal with, and it’s not unusual for homeowners to elect to replace their flue liners to get rid of it. This kind of creosote looks like tar running down the inside of your chimney. It’s a highly concentrated fuel that hardens and can form a thick layer when not properly cleaned. The cause of third degree creosote is burning wood when the flue isn’t warmed and temperatures in the flue are too low. Deposits of this type of creosote are also the result of incomplete combustion.

Minimizing 3rd Degree Creosote Deposits

To avoid having to deal with third degree creosote, it’s recommended that homeowners avoid burning unseasoned firewood and make sure there’s enough air for combustion to occur in the fireplace. Another cause of this problematic type of creosote is an improperly sized flue; there are restrictions on the size a flue should be for a wood-burning appliance. Because of this, it’s best to hire a professional with knowledge of these restrictions to handle all of your fireplace servicing needs to ensure everything operates properly.

Safely Removing 3rd Degree Creosote Deposits

Creosote Buildup in Metal Flue - Asheville NC

It’s very difficult to remove third degree creosote. A rotary head with chains can typically get the job done and is considered a safe method; however, any flue liner damage that may or may not have already existed is often attributed to this method by many disgruntled customers. If only there were a safer method for cleaning these dangerous deposits. Alas, there is! We’d like to introduce you to SaverSystems Poultice Creosote Remover (PCR). This is a revolutionary product designed to completely remove third degree glazed creosote from flue tiles or stainless steel chimney liners and eliminated the need for dangerous and potentially destructive cleaning methods. PCR can be applied by brush in areas that are easily accessible or with a specially designed tool that can be pulled up through the chimney by a winch. Once applied, PCR dissolves the creosote and then absorbs it. As it absorbs the creosote and then dries, it loses its adhesive properties and simply falls off the sides of the flue tiles. A less aggressive form of chimney sweeping can easily remove any remaining PCR.

A chimney inspection can help determine if creosote buildup is a problem for you.
