Now you can remove the cooking surface and have a look at the lava rock or ceramic briquettes. If they look a little grubby it's usually best to change them for a fresh set. They will last for many years, but a fresh batch at the beginning of every season will improve the look and performance of your barbecue grill.
Briquettes will work with all gas barbecues and are preferable to lava rock because the even shape gives a superior spread of heat and reduces flare up. Their smooth curved surface allows the barbecue juices to vaporize evenly with any excess escaping easily, rather than sitting in the pores of lava rock, heating up and catching fire.
