As you snuggle in to enjoy your gas fireplace this fall, you may notice that a white, cloudy build-up has developed inside of the glass. The good news is that this build-up is normal.

Follow these simple steps to quickly clean the glass on a gas fireplace.

How to Clean the Glass on a Gas Fireplace

Cleaning the glass on your gas fireplace is an important step to maintaining your fireplace. The entire process should take no more than 15-30 minutes and will do wonders for the appearance of your gas burning fireplace.

Before you get started:

Clean white residue of gas fireplace glassBefore you remove the glass from the gas fireplace, it’s important to take note of these important safety measures and precautions.

  • Turn off the gas. Don’t attempt to clean the glass on a gas fireplace with the pilot light still lit. Completely turn off the gas for your safety.
  • Do not use abrasive cleaners. If it has been a while since you’ve cleaned your gas fireplace glass, you may have heavy white build-up on the glass as pictured. Don’t make the mistake of using abrasive cleaners to remove the build-up. This will leave scratches and compromise the integrity of the glass.
  • Ensure the glass is completely cool. Don’t attempt to remove or clean the glass until the fireplace is completely cool. You don’t want to burn your hands or crack the glass as you attempt to clean.

Clean the inside of the glass:

  • Remove the decorative front and / or grills. The decorative front will likely be clipped on to the frame. Carefully remove the front and place it to the side.
  • Release the spring clips that hold the glass. On the bottom of the fireplace, you’ll see that the glass frame is secured with spring clips. Release the spring clips and gently pull the glass off of the fireplace.
  • Place the glass on a soft surface. Place the glass on a non-scratch surface like a towel, blanket, or carpet.
  • Use a glass cleaner formulated for fireplaces. For best cleaning results, use a glass cleaner designed for cleaning fireplace glass. Apply the cleaner directly to the glass and rub it in. Allow it to dry (about 10-15 minutes). Rub the glass cleaner off. The white film should no longer be visible.
  • On the outside of the glass, use a non-ammonia window cleaner. To remove fingerprints and smudges from the outside of the glass, use a non-ammonia cleaner only. Do not use ammonia!
  • Reinstall the glass and decorative front.

Other important precautions:

If you notice black soot build-up on the inside of your gas fireplace, contact the dealer for service right away. This is a warning sign that there is an issue with the fireplace combustion process.

If you notice small cracks in the fireplace glass, the glass should be replaced right away. The cracks indicate a weakening of the glass.
