Burner health is the most critical component to cooking performance and even heat. Use the venturi brush to clean out the burners; bugs love to build nests inside them cutting off your gas fl ow. The fine detail brush is the easiest way to clean-up burners, the collector box, or any hard to reach spaces. The fine detail brush also has a needle tip to clean out any clogged burner tube holes – essential on rotisserie burner grills.
