Do Chimney-Cleaning Logs Really Work?

Chimney Cleaning Logs in Amherst, NHThe fact that there’s such a product as chimney-cleaning logs tells you that cleaning built-up creosote out of chimneys is an important job. Chimney-cleaning logs are burned like any other logs but have special ingredients that are said to remove creosote. Sounds easy and simple. But do the logs actually work?

Look for CSIA-approval

Just because a product calls itself a “chimney-cleaning log” doesn’t automatically mean it will do a good job. Some brands bear the inscription “CSIA Accepted Product.”  CSIA stands for the Chimney Safety Institute of America, the leading agency covering chimney safety and the hearth industry in general.

If you’re going to try chimney-cleaning logs, definitely purchase those accepted by the CSIA. But you may notice some other wording from the institute on the log label that states something to the effect of: these logs are not a substitute for annual chimney inspection and cleaning.

Drawbacks to chimney-cleaning logs

Because these logs cannot replace cleaning performed by CSIA-certified chimney sweeps – technicians who make their livings cleaning chimneys and making them safe – a chimney-cleaning log set can give you a false sense of security.

No matter how much creosote can be removed by burning special logs, it’s not enough to satisfy the CSIA, which provides stringent industry certifications to technicians who have demonstrated exceptional skill and knowledge in the areas of chimney cleaning, inspection and repair.

One big problem with chimney-cleaning logs is that you can’t know exactly how well they’ve worked. Unless you can see inside your chimney, it’s impossible to know what did or didn’t happen in there after you burn cleaning logs. This means you really don’t know how much creosote may still exist inside the flue.

Another drawback is that as the burning logs dislodge creosote, the flammable substance can fall down into a roaring fire, which is like throwing lighter fluid on the flames.

If pieces of creosote don’t hit the flames, they may start stacking up on the smoke shelf just above the firebox. In this case, you still have a large amount of creosote in your chimney, only in a different place.
