Remove any debris with a soft brush. Use back and forth motions to brush gently but thoroughly until all debris has been removed. For particularly stubborn debris stuck in tiny gas flow channels, use a toothpick to dislodge the debris.
Spray the table with all-purpose cleaner. Use a cleaning cloth to wipe down the entire table, including the tabletop, fire bowl and table legs.
Wipe off the gas logs, gently, with a damp cleaning cloth. Replace them in the fire bowl.
