Maintaining a clean chimney isn’t just a matter of efficiency — it’s about safety. Creosote buildup inside chimneys is the leading cause of chimney fires. Many homeowners wonder: Is there something you can burn to clean a chimney?
Short answer: Yes, but it’s only part of the solution.
Certain products and materials can help reduce creosote buildup, but none replace regular inspections and professional cleanings.
Let’s dive deep into what you can burn, how effective it is, and what you need to know to keep your chimney safe and functional.
When you burn wood, it releases smoke full of gases and particles. As this smoke rises up a cooler chimney, it condenses and forms a sticky, flammable substance called creosote.
There are three stages of creosote:
Burning certain things can help manage Stage 1 buildup, but nothing easily removes Stage 3 without specialized tools.
Skipping chimney maintenance is gambling with your safety.
Yes, but with limitations. Certain materials can help loosen or reduce creosote, making it easier to clean during your annual inspection or service.
However, burning alone is not enough. Think of it as maintenance between professional sweeps, not a substitute.
What they are: Logs infused with chemical compounds that reduce creosote adhesion when burned.

If you prefer not to use chemical products, some natural options may help minimize creosote accumulation:
Best wood choices:
Why:
Tip: Wood should be seasoned (dried) for at least 6–12 months.
Myth or Fact? Some old-timers swear by tossing salt into a roaring fire. While it may loosen soot slightly, salt alone isn’t a reliable cleaning method.
Important: Natural methods may help a little but don’t replace professional sweeping.
Trying to clean your chimney by burning certain materials can backfire badly:
Stick to proper materials. Bad choices can cause faster buildup or even start chimney fires.
Best uses:
Limitations:
Analogy: Think of burnable cleaners like brushing your teeth. It helps a lot but doesn’t eliminate the need for a professional dental cleaning now and then.
Rule of thumb: If you burn wood regularly, have a professional inspection at least once a year.
If you want to stay proactive:
Even if you use cleaning logs, book a certified chimney sweep once a year.
Always burn dry, seasoned hardwood.
Small, smoldering fires produce more creosote. Aim for hot, clean burns.
These parts prevent moisture damage and blockages.
Helps you keep fires in the safe, efficient temperature range.
You can buy homeowner-level chimney brushes for $50–100. Use extreme caution, proper tools, and safety gear.
John relied solely on cleaning logs for five years without inspections. One winter, his chimney caught fire due to Stage 3 creosote. Luckily no injuries, but repairs cost $15,000.
Lesson: Cleaning logs are helpful but not enough alone.
Emma used seasoned oak, burned creosote remover logs quarterly, and booked annual cleanings. Her sweep reported only minimal buildup year after year.
Lesson: Consistent maintenance prevents major issues.
Mike burned green pine and household trash to “clean” his chimney. Result: thick resin buildup, horrible smells, and dangerous flue cracks.
Lesson: What you burn matters.
Can you burn something to clean a chimney?
Yes — but cautiously and as part of a bigger maintenance plan.
