Getting back to the question question of “do those chimney sweeping logs work?” the first part of the answer is yes, they do work BUT do no replace a proper sweep!
These types of logs contain a chemical catalyst with can reduce the early stages of creosote buildup up to 60% with repeated use throughout the burning season
Even though the chimney sweep log will make the job easier, it isn’t enough. A log cannot replace everything that a certified and trained chimney sweep does .. that's a fact
They recommend a cleaner log one a month or every 60 fires, it certainly makes it easier for the your sweep when the times comes!
