Chimney Brush: Keeping Your Sauna Chimney Clean and Safe
A chimney brush is a round or square wire-bristle brush sized to fit your chimney pipe. You push it through the pipe to scrape off creosote and soot that accumulate on the interior walls. Regular chimney sweeping is one of the most important maintenance tasks for wood-burning sauna owners, and a chimney brush is the tool that makes it possible.

Why You Need to Brush Your Chimney
Every time you burn wood, combustion byproducts coat the inside of the chimney pipe. This buildup - especially creosote - is flammable. If enough accumulates and ignites, you get a chimney fire. Chimney fires can reach 2,000 degrees Fahrenheit and can damage the chimney, spread to the sauna structure, or worse.
Beyond fire risk, creosote buildup restricts airflow through the chimney, reducing draft and making your stove less efficient. A clean chimney draws better, meaning cleaner burns and faster heat-up times.
Choosing the Right Brush
- Size: Match the brush diameter to your chimney pipe's inside diameter. Most sauna stoves use 4-inch, 5-inch, or 6-inch pipe. The brush should fit snugly but not so tight that you can't push it through
- Bristle material: Wire bristles for metal chimney pipes. Polypropylene (nylon) bristles for stainless steel lined chimneys, as wire can scratch the liner
- Rod type: Flexible fiberglass rods that screw together in sections let you push the brush the full length of the chimney from the bottom. Some people prefer working from the top down with rigid rods
How to Clean
- Let the stove and chimney cool completely
- Remove the chimney cap or disconnect the chimney pipe from the stove (depending on which approach is easier for your setup)
- Attach the brush to the first rod section and push it into the pipe
- Add rod sections as needed and push/pull the brush through the entire length of the pipe several times
- Collect the fallen soot and creosote from the stove or a collection tray placed below the pipe opening
- Reinstall the chimney cap and reconnect the pipe
How Often
For a sauna that gets used 2-3 times per week, clean the chimney at least once per season. If you burn softwood or notice reduced draft, clean it more often. A quick visual check once a month (shine a flashlight up the pipe) tells you whether buildup is getting heavy.
