Make relaxation your top priority

Co-Mate Chimney Cleaner is a powerful formula of carefully sourced and modified mineral compounds. When introduced into a hot fire, Co-Mate will react with the burning wood as creosote is formed. Creosote is normally a sticky black substance that adheres to the inside walls of your chimney. Over time, this substance becomes a major fire hazard.


Co-Mate changes the physical structure of creosote, significantly reducing its flammable nature while making it much less likely to accumulate inside your chimney.


With regular use, Co-Mate can help keep your fireplace or wood stove a safe and effective part of your home or business while extending the overall life of your heating appliance.




Co-Mate Chimney Cleaner is the simplest and most effective way of keeping the chimney of your wood burning appliance clean all year round.

Co-Mate's powerful formula is derived from years of research and development in industrial applications.

The product is a coarse, free-flowing powder that is activated by the heat of the fire inside your appliance to actually enhance combustion chemistry. Co-Mate utilizes unique physical processes rather than harsh chemicals to achieve incredible effects.


For use in:

  • Wood Stoves

  • Fireplaces

  • Pellet Stoves

  • Wood Furnaces

  • Coal-fired Units

Works Universally

Whether you are using an old and inefficient fireplace burning poor quality fuel, or you have a state-of-the-art EPA certified wood stove operating in the best of circumstances, burning wood means soot and creosote accumulation is a fact of life. Co-Mate is safe to use in all types of wood burning appliances, chimneys, and inserts.


Works Powerfully

Co-Mate is great for keeping your wood burning appliance clean and working at peak performance. The effects are even more dramatic when used in less than optimal conditions such as low-firing or when using a poor quality or wet fuel.


Works Effectively

Co-Mate works great to help clean a dirty chimney, but you can enjoy all of Co-Mate’s benefits by using it to keep your clean chimney clean. While you can use Co-Mate to loosen and destroy creosote buildup, we recommend having a trained professional inspect and sweep your chimney first, especially in cases of extreme fouling. Remember, Co-Mate works as an ash modifier, rendering creosote inert and mostly harmless, and unable to adhere to heating surfaces.


Works Reliably

Sprinkle a little Co-Mate onto the fire on a regular basis for optimal and consistent results. Using Co-Mate on a regular basis will help keep creosote from forming in the first place. Keep your wood burning appliance working as clean and efficient as the first day you bought it.

Co-Mate does much more than simply clean your chimney

Co-Mate itself is non-polluting and helps to promote a cleaner environment around your home. When used regularly, Co-Mate reduces particulate emissions and annoying odors leaving your chimney. It also neutralizes the acidity of ash and over time protects your chimney from corrosion. Overall, Co-Mate helps your entire system run cleanly and efficiently, meaning a more even and continuous heat from your appliance all year round.

“Thank-you for all your assistance related to a blockage in my chimney from a heavy build up of creosote.  I used a generous amount of Co-Mate on a hot fire and sure enough your product broke the build up down and I was able to sweep the chimney clean. Would highly recommend this product to any one that has a creosote problem."

"We had a wood stove installed one year ago.  Had it cleaned just before our burning season this October, and the cleaner said our chimney was VERY clean - and attributed it to Co-mate."
