Soot forms naturally during combustion of the gasses and can only be reduced by burning less gas in your fireplace. A vent free set will burn less than a vented set and as a result will soot less.

Soot is a natural byproduct of combustion and will inevitably form when gas is burned in a fireplace. While it cannot be completely eliminated, the amount of soot produced can be minimized by adjusting how the fireplace is used. For example, vent-free gas log sets typically burn less gas than vented sets, which results in reduced soot accumulation. However, it’s important to understand that all gas log sets—whether vented or vent-free—will produce some level of soot over time. The more frequently the fireplace is used, the more soot will accumulate on the logs, fireballs, or decorative elements.

Fortunately, removing soot is a relatively simple process. One effective method involves gently heating the set before cleaning. First, turn on the fireplace for a few minutes to allow the logs or fire media to warm up. Once they are warm (not hot), use a spray bottle to lightly mist the sooted areas with water. Then, turn off the flame. As the moisture combines with the residual heat, much of the loosened soot will lift away and exit through the vent or chimney.

Alternatively, soot can be removed when the fireplace is completely cool. The components can be taken out and cleaned manually using a soft brush and mild detergent. However, this method is generally not recommended for frequent maintenance, as it increases the risk of damaging the decorative surface or misaligning the setup.

Regular cleaning helps maintain the visual appeal and efficiency of your fireplace, especially if you use realistic ceramic logs, fireballs, or fiber-based decorative elements. While soot is unavoidable, proper care ensures your fireplace continues to operate safely and look great for seasons to come.
