You do not need to do anything to the carbon steel to maintain it's finish. If you would like to smooth out the weathered surfaces, you can use a Scotch Brite pad to gently rub the steel. This will cause some of the rust barrier to break off and fall to the ground. Be sure to thoroughly clean the ground surface after this process. You can use water to clean the surfaces after this process.

Do not get water into any of the burner components. Water in the burner components can cause dangerous back pressure. If you think there is water in the burner components, call a licensed technician to check the burner before use.

Fire Pit with Gas Option
Fire pits should be inspected before initial use and inspected and cleaned at least annually by a qualified field service person. Periodically remove the logs, glass or lava rock and examine the burner. If dirty, clean with a soft brush. Also, examine the area around the Propane/Air Mixer. Any dirt or lint in this area should be removed. This will ensure long life and trouble free operation. When the fire pit is put back in service, check the burner flame patterns; it is imperative that the burner flame characteristics are steady, not lifting or floating. Periodically check the hose connecting the LP gas cylinder to ensure it is not damaged in any way. While the fire pit is not in use, it should be covered to protect it from weather and other adverse elements. Not protecting the fire pit could result in a void of the warranty.

Carbon (soot) may build up on the surfaces of the logs with heavy use. This is more likely to occur when using LP gas. The soot should be cleaned off the surface of the logs periodically to prevent excessive buildup. To clean the logs, be sure the fire is out, the gas supply is turned off and the logs are cool to the touch. The soot can then be brushed off with a dry bristle brush or cloth. Logs can be damaged if mishandled. Dispose of soot and cleaning materials properly. Keep away from clothing, pets and outdoor furniture.
