Why clean your grill burners
Most people prepare your barbecue grill type for heavy use in the summer, during spring cleaning grates. Many people, however, neglect cleaning the grill burner, where the flame comes out. It is a good idea you check the burner annually to see if dirt and debris have covered some of the holes and their accumulation can lengthen cooking times, and can also be dangerous.
Disassembling the grill
Begin by removing the grill. Make sure you shut off the gas and purge the lines before beginning this process. Remove the grates and lava rock grill, which will expose the metal burner underneath. You can clean the grates and lava rocks at the same time you clean the burner, you using the same methods as described below. Finally, remove the burner cap.
Cleaning your grill burner
To clean the burner, make a solution of about a cup of white distilled vinegar for every gallon (3.75 L) of hot water and a teaspoon of dish detergent (one that will work best cutting fat). Sprinkle this on top of the burner. If it is very dirty, let it soak in a bowl with the vinegar solution. Scrub the grease and dirt from the burner with a brush, making sure all burner ports are free of dirt. Repeat this as many times as necessary until it is clean.
Reassembly of the grid
Reassembling the burner and turn on the grill to see if it is working properly. The flame should be blue, not yellow. If it is yellow, check the burner again (after it has cooled) to make sure it is clean enough.
