Things have been pretty hectic around here, but let me see if I can squeeze in a tip or two about lava rocks and ceramic rocks.
Unlike flame tamers, lava rocks actually need to be changed once in a while. Why? Well, when the oil from your grill drips down onto the rocks tray, your rocks will absorb it, making it less efficient when it comes to dispersing heat.
How often should you change your rocks, you ask? It depends on how frequently you use your barbecue. Obviously, the less you use it, the less often you’ll have to change it. On average, a household would change their lava rocks about once every 6 to 8 months. If you want to be more sure, turn on your fire. If your grill doesn’t seem to be giving off as much heat as it did when you first purchased it, then it’s time to throw out the old stuff!
