Do chimney sweeping logs really work?

It isn’t really the logs that are supposed to do anything, it is the chemicals they’re impregnated with.

Chemical products that claim to clean or assist in cleaning chimneys, are nothing new.  In fact, there are actually some chemical products that

are used by professional chimney sweeps, in conjunction with mechanical cleanings.  Specifically, in some extreme situations, a chimney can

develop 3td. stage glaze creosote that is so hard that it cannot be removed by brushing alone.  In these cases, certain liquid chemicals catalysts may

be sprayed directly onto the glaze to alter its chemicial composition, turning it into a brittle or powdery condition, so that it can be swept out by a

professional chimney sweep.

We have a couple of problems with the marketing of these logs.  1st. their name is misleading—–you would think that a product called ” Chimney

Sweep log would sweep your chimney, or at least perform an equivalent function.  ( The actual claim in small print is that the chemical contained

“might” reduce creosote by “as much as 60%”.)

2nd.  We have not found the chemical catalysts to be of any use whatsoever on 1st and 2nd stage creosote deposits, which comprise about 90% of

the deposits we fine in chiomneys.

Even if your flue was coated with glaze cresote and the chemical in the “chimney sweep log” broke it down 60%, it would still represent a

considerable safety hazard until it is physically re,oved by a professional sweep.
