Cleaning those burners is often forgotten.

Today we will share how to clean the burner tubes of a Weber gas grill so they continue to heat the food properly.

1): Brush The Grates

Brush The Grates

All burners need to be turned up to HIGH, and the grates need to be burned off for 10-15 minutes. The grates’ top side should be cleaned using a grill brush. Then flip the grilling grates over and brush the backside once they are cool enough to handle safely. Grates should be removed and set aside.

2)Scrape The Flavorizer Bars

Scrape The Flavorizer Bars

Utilizing a wide putty knife, scrape both sides of each Flavorizer bar into the grill after it has cooled sufficiently. It is essential to examine every bar. The food drippings and high temperatures that Flavorizer bars are exposed to cause the bars to rust often. It is not necessary to replace them until the rusted part of the casing wears through and breaks. Once you’ve scraped the Flavorizer bars, put them aside.

3): Scrape The Upper Firebox

Scrape The Upper Firebox

Remove debris from the back and sides of the upper firebox by scraping it with a wide putty knife, which will allow it to fall into the grill. Sweep the ledges, nooks, crannies with a stainless steel wire brush to dust the upper firebox.

4): Clean-Out The Ignitor Boxes

Clean-Out The Ignitor Boxes

Make sure that the ignitor boxes are cleaned with a compressed air duster. The ignition assembly in each box should be replaced if rusted through. This will allow the grill to light quickly.

Clean The Burners & Crossover Tubes

Clean The Burners & Crossover Tubes

For cleaning the burner tubes and crossover tubes, use a stainless steel wire brush. Please make sure the bristles of the brush penetrate the holes to clean them. Be particularly careful about the holes leading from the ignitor box to the burner’s top as well as the hole leading to the Burner’s Crossover tube. When these holes are blocked, it’s hard to light the grill and the secondary burners.

Even if you brush the top of the burner, a few holes are likely to remain clogged. Using an eyeglass screwdriver or paper clip, punch down on the debris to remove it.

Scrape The Lower Firebox

Scrape The Lower Firebox

The lower firebox below the burner tubes should be scraped with a narrow putty knife. Remove the debris from the grill and place it in the bottom tray. Dust with a compressed air duster if there is any debris that can’t be reached.

Brush Inside The Lid

Brush Inside The Lid

Remove any flaking material inside the grill lid with a grill brush or aluminum foil wad. The flakes are made up of carbonized grease that builds up during grilling and eventually falls off. Neither rust nor paint is corroding.

Reinstall The Flavorizer Bars & Cooking Grates

Reinstall The Flavorizer Bars & Cooking Grates

The Flavorizer bars and cooking grates can be reinstalled inside the firebox now that everything has been cleaned. The Flavorizer bars may need to be reinstalled in a different order, so they wear out more evenly. Swapping the edge bars for the center bars might do the trick.

Clean The Bottom Tray & Drip Pan

Clean The Bottom Tray & Drip Pan

Each grill model has a different bottom tray shape and size. The one shown here is a narrow one covered with porcelain enamel. Stainless steel is sometimes used. A bottom tray serves as the entire bottom of the grill box on older models like Genesis 1000. This is to emphasize that your bottom tray may not look exactly like the one shown here.

The bottom tray needs to be removed from the grill. Using a putty knife, scrape the tray contents into a trash bag, then wipe away any remaining grease with paper towels. You should discard any oil that was not contained by the foil drip pan liner, and you should discard the foil drip pan liner. Wipe off any fat and debris with paper towels after removing the drip pan brackets.

Before Reassembly

The assembly process begins once everything has been finished, including the finishing touch. Hold on a moment. Achieving our goal is almost here. The gas line should be connected to your burner, and the flame should be operating correctly. Then, cook plates and grates can be attached.

Additionally, turn the grill off later and replace the residing parts. If you see too many yellowish flames or what appears to be zero flames, you will need to do some adjusting.

Adjust the air setting and then try to transfer it. On the grill burner, this is available. For a flame to work, there must be an infallible blend of oxygen and gas. A lovely blue flame will appear once it’s good!
