How to Clean a Gas Fireplace
Gas fireplaces give warmth without the smoke or ash of a wood fireplace. It’s a quicker, more energy efficient way to heat a room than a gas furnace is. However, a gas fireplace can get grimy over time. Burning gas can cause a fireplace’s glass door to turn white or foggy due to the manufacturing chemicals used in natural gas products. Here is a basic gas fireplace cleaning process:
- Turn off the gas valve. Let the burners cool completely before cleaning.
- Vacuum out any dust and debris from around the fireplace and/or its vents.
- Open the fireplace door or doors. Use a dry paint brush or cloth to dust off the ceramic gas logs and any decorative fireplace grate.
- Clean the glass doors with glass cleaner and paper towels. If there is a white film, consider using a special fireplace glass cleaner instead.
- Give the andirons and tools a thorough cleaning with dish soap and water. Follow up with metal polish if desired.
Tip: Soot can build up in a gas fireplace if the logs or ports aren’t working properly. Contact a plumber to make sure your gas fireplace is in good condition.

How to Clean a Wood-Burning Fireplace
Many traditional fireplaces, especially in older homes, burn wood. Wood provides a traditional crackling, roaring fire. The more you use it, the more ash, soot and creosote builds up. There’s nothing inside a wood-burning fireplace except a metal grate. It will have a damper but may or may not have a built-in screen or glass doors.
Here’s how to clean a brick fireplace that burns wood.
- Extinguish any fire. Spread out the embers with a fireplace shovel. Cover embers with ash or a little baking soda. Wait 24 hours.
- Make a deep cleaning solution. Combine dish soap, 1/4-cup of heavy-duty cleaner and 1 gallon of warm water in a large bucket.
- Use your hands and a fireplace shovel to remove burnt wood.
- Remove the andirons and fireplace grate. Knock off as much ash and debris as possible back into the fireplace.
- Sweep up ash with a broom and dust pan. Use a hand vacuum, shop vacuum or vacuum hose to thoroughly remove residue.
- Scrub inside fireplace with a stiff bristled brush and cleaning solution. Work from the top down. Repeat this process a few times if necessary.
- Clean the bricks on the fireplace surround with a pumice stone dipped in dish soap. For particularly stubborn soot stains, try a trisodium phosphate cleaner.
- If you have glass doors, clean them with glass cleaner and paper towels. Or learn how to clean fireplace glass with wood ash. Dip a paper towel in warm water and then ash. Rub the glass until it is clean. Rinse and polish with a paper towel.
- Allow your fireplace walls and floor to dry thoroughly.
- Clean the andirons and tools with dish soap and water. Follow up with metal polish if desired.
Tips on Cleaning a Fireplace
- Sweep around and shovel your wood-burning fireplace once a week. Leave about an inch or so of ash. It insulates the embers and helps them burn hotter.
- Dust gas and electric fireplaces once a week and clean the glass.
- The National Fire Protection Association recommends that chimneys, fireplaces, vents and flues are cleaned and inspected a minimum of once a year. A good rule of thumb is to do it when the weather turns cold.
- Opt for a professional chimney inspection and cleaning. This will rid your wood-burning stove or fireplace’s chimney of highly flammable creosote buildup. Chimneys, dampers and flues can also develop mechanical or structural issues.
- Gas and electric fireplace chimneys should also be professionally checked once a year. Animals and birds can build nests in them and this too can cause a hazard.
- If you have a stainless steel chimney liner, the CSIA (Chimney Safety Institute of America) recommends cleaning the liner once it has about a 1/8-inch of soot or creosote buildup.
- Hire a plumber to inspect your gas fireplace line once a year to ensure it is working correctly and the logs are positioned properly.
- Invest in a carbon monoxide detector and make sure it works.
- Think about using a chimney cleaner, chimney soot remover or fireplace cleaning log in a wood-burning fireplace regularly. It can reduce tar and creosote buildup in your chimney walls.
- Creosote can have an odor in high humidity months. Consider using a chimney deodorant or try placing a container of kitty litter and baking soda in the fireplace.
- Use a metal fireplace screen to block popping embers from scorching the hearth or floors.
- Install a chimney cap to block birds, leaves and animals from entering the chimney.
- Always supervise a fire. Keep children and pets safe.
Knowing how to clean a fireplace isn’t difficult. With minimal materials, you can clean your wood-burning or electric fireplace in an afternoon. Always start by covering your work area with a drop cloth or plastic tarp. Move any furniture and rugs. Have a trash bag or bucket nearby. Wear cleaning gloves, eye protection and a face mask, especially if you are using any strong cleaners.
