New and Improved

The new and improved triple action formula fights dangerous creosote accumulation.

  • Treats existing creosote in your chimnrey
  • Reduces new creosote build-up, making your next fire safer.
  • Eliminates odors that linger during off-season.

Regular chimney inspection is always recommended. The Creosote Sweeping Log will not tell you if your chimney is blocked or has any kind of structural damage. The Creososte Sweeping Log does not take the place of inspection and professional cleaning.


Our personal favorite when it comes to high class woodstoves are JØTUL woostoves.

It works!

I use two of these logs through out the burning season. It does loosen up the soot build up making it easier the clean the chimney, which I do once a year with a stiff chimmney brush.

Best deal

This was the best price I could find for these logs. We bought a house and didn't use the chimney for two years.... bought these and burned one the other day, seems to have done the trick. No complaints.

Efficient as expected

The Creosote Sweeping Log works very well. They light readily and burn well, treating the existing creosote on the inside of the stove and chimney. Thereafter, the creosote hardens and falls off into the ash pile and burns up.
