Are you not getting the best performance from your Weber Gas Grill? Has the pre-heating temperature not been going beyond 400°F when it used to reach 550°F? It could be that the burner tubes are clogged and need to be cleaned. Here is how to clean Weber gas grill burner tubes to keep your gas grill working in top shape.

Weber gas grills are incredibly tough and durable. Many Weber gas grill owners often think that when the grill does not operate at peak performance, the burners need replacement. This is not the case all the time.

When your grill burners are cracked, falling apart or burner potholes seem connected to each other, you will need to replace these burners. Rusty or clogged burnerson the other hand just need some cleaning especially the gas burner tubes.

The burner tubes of most Weber gas grills are located below the heat deflectors or flavorizerbars. Burner tubes allow gas to flow to the burner.  The burner tubes are also responsible for allowing the burners to provide even heat all throughout the grill.

While you are grilling grease, marinade, juices and sauces from the food go the flavorizer barsand eventually to the cookbox. While the burners are protected from these drippings, over time, surface corrosion will occur and the burner tubes will start to get clogged. These will lead to uneven heat inside the grill.

If your Weber gas grill is not having even heat (there are hot and cold spots), this means the burner tubes are not functioning well. Deposits in the burner tubes need to be removed to allow the normal flow of gas to the burners.

Cleaning Gas Grill Burner Tubes

Dirty or clogged burner tubes are caused by scaling of the burner tubes. Scaling is caused by grease, dirt, carbon, moisture, and oxidation and of course from cooking over time.

Scaling causes the ports or holes in the burner tubes to be smaller (other portions of the ports or holes have been covered by dirt and debris) and provide lesser flame. A visible proof of dirty or clogged burner tubes is a yellowish-orange colored flame.

Brushing the burner tubes of your Weber grill will keep it free from any debris and oxidation. You should do these at least once a year or at least every quarter if you often grill the entire year.
