Lava rocks used in gas barbecue grills should not be washed in water or put in the dishwasher. Instead, they should be cleaned by burning them clean. Turn the lava rocks carefully over so that the greasy side is facing down.

Do this only when the grill is completely cool. Lay some aluminum foil over the grill grate. This will help trap the heat in for a more efficient cleaning. Turn the grill on high for up to thirty minutes. After it stops burning or the half hour is up, turn off your grill and let it cool down. Once the lava rocks are cool, remove them from the grill and brush off any remaining debris.

If the lava rocks are breaking apart, it’s time to replace them rather than attempting to clean them.

Best Way to Clean the Lava Rocks in a Gas Grill: Step-By-Step

Cleaning lava rocks in a gas grill is like giving your trusty sidekicks a spa day to ensure they perform their best during your grilling adventures. The easiest and safest method I’ve found involves burning off the grease. Here’s a simple step-by-step guide to get your lava rocks squeaky clean:

Step 1

Let It Cool Down – Post-Grilling Chill Time: After your grilling session, switch off the burner and give your lava rocks a breather. They need to cool down, so let them relax.

Step 2

Flip the Script – Grease Down: Once the lava rocks are cool, grab a pair of tongs and flip them over. Make sure the greasy side is facing down toward the burner. It’s like giving them a new perspective on life.

Step 3

Foil Magic – Wrap ‘Em Up: Get a piece of aluminum foil large enough to cover all the rocks. Lay it over the grill, and it’s like your lava rocks are getting cozy under a warm blanket. The foil helps radiate the heat inward, which is what we need.

Step 4

Heat Things Up – Turn On the Burner: Fire up the burner and watch the magic unfold. The foil traps the heat, and it will start to burn off the grease. You might see some smoke escaping from beneath the foil – that’s a good sign. It means your rocks are shedding their greasy baggage.

Step 5

Patiently Wait – Let the Grill Work Its Magic: Leave your grill on, with the lid open, for about half an hour. It’s like a lava rock spa day. If you still see some smoke after that time, and the rocks look greasy, let them keep burning for another 30 minutes. Be patient – it’s worth it.

Step 6

The Grand Reveal – Clean Lava Rocks: After your patience pays off, your lava rocks should be clean and ready for action. Your grill will be as good as new, and you’re all set for the next grilling masterpiece.

So, there you have it – a safe and straightforward method to clean your lava rocks. Happy grilling, and may your grilling adventures be smokin’ good!
