How To: Gas Log Cleaning

How To: Gas Log Cleaning

Although propane and natural gas are clean burning fuels, your gas log set will still need a good cleaning! Dust, dirt or pet debris can dull the appearance and diminish your fireplace’s function over time. It is recommended that a gas log set gets refurbished every 2-3 years for maximum performance. With a little motivation and the right products, your gas fireplace will look like new in no time!

You will need the following replacement products:

  • 10-Pound Bag of Silica Sand (or 1.5-Pound Bag of Vermiculite for LP)
  • 10-Pound Bag of Lava Rock or Fire Glass
  • 1 Bag of Embers


  • First, turn off the gas before beginning. If the fireplace has been recently used, allow enough time for all components to completely cool. Double-check that the pilot light is out and wait a few extra minutes. This will ensure any residual gas has left the piping.
  • Next, disassemble the logs and carefully remove the burner unit. Before you physically remove the logs, locate the owner’s manual or take photos of log placement. This will ensure correct assembly later. Place the logs on a tarp or take them outside. Importantly, take caution not soil carpeting or other flooring. Remove the glass/rock, sand and embers from the fireplace. This can be done with a vacuum or simply by scooping out the material with a small shovel and garbage bag.
  • After disassembly, clean the logs of dust and soot. In order to avoid unnecessary messes, it is suggested that you perform this task outdoors. The easiest way to clean logs is by using a shop vac with HEPA filter. Using the shop vac with a brush attachment, gently clean each log. If a shop vac isn’t readily available, a small handheld horse hair broom (or other soft broom) works well, too. If using a broom, gently sweep it back and forth across each log. Repeat until each log is visibly clean.
  • Finally, clean and inspect the inside of the fireplace. Using the shop vac, clean out any residual dirt and dust. Pay close attention to corners and be sure to remove any cobwebs. Most gas fireplaces have glass doors that will become dirty over time. It should be noted that a standard glass cleaner, oven cleaner or other harsh chemicals are not recommended. Subsequently, a specialty fireplace glass cleaner is suggested. Following the product directions, clean the inside and outside of the glass.


  • Inspect the gas connection. In addition to the gas log cleaning, it is vital to inspect all components. Check the wiring for any visible kinks. Additionally, take a moment to ensure all connections are tight. In compliance with most manufacturer warranties, we suggest that all essential components be inspected by a certified professional. This includes the pilot, gas valve, thermocouple/thermopile, burners and wiring. A technician can also verify that your gas fireplace is properly vented.


  • Lastly, reassemble your fireplace. If your unit contains a remote control, be sure to replace the batteries. Using the manual as a guide, replace the burner, sand (or vermiculite), glass/lava rock and embers. Again, while consulting the manual (or referencing the photos from earlier), arrange the newly cleaned logs in their proper places. Once all components are returned to their proper locations, you may turn the gas back on.
