Creosote Must Be Minimize – Creosote has three stages. As each stage increases, they become more hazardous and are increasingly difficult to remove from the flue.
Stage 1 – The first stage of creosote is like flaky soot that is easy to brush away with a basic chimney brush.
Stage 2 – Creosote in the second stage can be described as shiny, hard black flakes. The flakes actually contain hardened tar that is not easily brushed away, but it can be removed without extreme measures. The most popular method for removing creosote in the second stage is with a rotary loop. A powerful drill turns metal rods that get the job done.
Stage 3 – Third-stage creosote is something to be avoided. Not only is it extremely difficult to clean, it is a highly concentrated fuel that resembles a coating of tar dripping down inside of your chimney liner. This type of glazed creosote can become very thick as it hardens and is repeatedly recoated with another layer. A hot fire can easily ignite this type of creosote, which is extremely hazardous.
If stage three creosote catches fire, it becomes easy to remove because it leaves behind a spongy residue. But, a chimney fire can too easily lead to a house fire because the intense flames often cause a fire on the roof or damage the flue, causing combustible parts of the home to ignite.
