Cleaning & Lubricating Weber Gas Grill Valves

Are the gas grill valves in your old Weber Genesis or Summit grill stiff and hard to turn? Do they no longer lock in the Off/High/Medium/Low positions? Do they not pop back up after being pushed down?

If you answered “Yes” to any of these questions, you can probably solve the problem by cleaning and lubricating the gas valves.

Genesis Platinum C Cleanup & Repair by Scott P

To the untrained eye, this circa 2005 Weber Genesis Platinum C gas grill looks like a piece of junk, ready for the scrap heap. But Scott P. from Porter, TX knew better. He picked it up on Craigslist for $50, gave it some spit and polish, and it’s ready for many more years of grilling.

Scott gave the grill a thorough cleaning inside and out, then removed the storage enclosure and did some repair to the floor pan using a rust converter, bonding primer, and graphite spray paint.

A little more polishing of the stainless steel and gray painted surfaces and this gasser was ready for action!

“The burners all work well. It got up to 500°F in about 6 minutes and 600°F a bit later,” says Scott. “I could have spent more time sanding and grinding to smooth out the rust and old paint, but I was looking to do this quick.”

What Scott calls “quick” I call “looks great”!

Repair Rusted Screw Holes With QuikSteel

It’s not uncommon to encounter a rusted-out screw hole when restoring an old Weber gas grill. How do you repair a rusted-out screw hole? In some cases, it’s easy enough to clean-out whatever remains of the hole and replace the original screw with a bolt and nut. But in some cases, you’ll want (or need) to repair the screw hole so the original screw can be used again.

Spider Screens: Inspection & Cleaning

Did you know that your Weber gas grill contains spider screens? Did you know that you need to occasionally inspect and clean them? If you didn’t know these two facts, read on.

When the performance of your Weber gas grill seems to be lacking—for example, it’s not achieving the high temps it used to—the first thing you should check is the condition of the burner tubes. If the tubes are covered with cooking debris and scale and the flame pattern is more yellow than blue, the burner tubes need to be cleaned.

Deep Cleaning Your Weber Gas Grill

In a post last year, I said I was a clean freak when it comes to my grill. But sometimes I get busy and/or lazy and I let my Weber Summit 450 go too long between cleanings. I know it’s starting to get bad when I have a hard time lighting the grill because the ignitors are clogged with debris. I know it’s getting even worse when the burners are burning unevenly and with yellow flames because some of the burner holes are clogged. That’s when I know it’s time to break down and do a deep cleaning of my grill.

Here’s how I do it.

Grill cleaning supplies & tools
Some of the supplies & tools needed to do a Weber gas grill deep cleaning

Grill Cleaning Tools & Supplies Needed

To deep clean your grill you’ll need the following tools and supplies:

  • Grill brush
  • Leather grilling  gloves
  • Narrow and wide putty knives
  • Stainless steel bristle brush
  • Eyeglass screwdriver or paper clip
  • Disposable latex/nitrile gloves
  • Windex, Simple Green or similar cleaner
  • Stainless steel cleaner
  • Compressed air duster
  • 0000 super-fine steel wool
  • Towels/rags
  • Garbage bag

During some of the steps shown below, you may want to wear disposable gloves to keep your hands clean.

Brush The Grates

Turn all burners to HIGH and burn-off the grates for 10-15 minutes. Use a grill brush to clean the top side of the grates. Let the grates cool enough so you can handle them safely with grilling gloves then flip them over and brush the back side. Remove the grates and set them aside.

Scrape The Flavorizer Bars

When the grill has cooled sufficiently, use a wide putty knife to scrape both sides of each Flavorizer bar into the open grill. Examine the condition of each bar. It’s common for Flavorizer bars to rust due to food drippings and high heat. They do not need to be replaced until they start to rust through and break apart. Set the Flavorizer bars aside after scraping.

See All About Flavorizer Bars to learn more.

Scrape The Upper Firebox

Use a wide putty knife to scrape debris from the back and sides of the upper firebox, allowing it to fall down into the grill. Use a stainless steel wire brush to remove any debris from the ledges and nooks & crannies around the perimeter of the upper firebox.

Clean-Out The Ignitor Boxes

Use a compressed air duster to remove debris from the ignitor boxes. Examine the condition of each box; if rusted through, consider replacing the ignitor assembly so that the grill lights easily.

Clean The Burners & Crossover Tubes

Use a stainless steel wire brush to remove debris from the burner tubes and the Crossover tubes. Force the brush bristles into the holes to clear them. Pay special attention to the holes leading from the ignitor box to the top of the burner and the holes leading from the top of the burner to the Crossover tube. It’s difficult to light the grill and the secondary burners when these holes are clogged.

It’s common for some holes in the top of the burner to remain clogged after brushing. Use an eyeglass straight blade screwdriver or opened paper clip to punch down into these holes to clear debris.

When the burners are clean, they should burn with mostly blue flames as shown in the photo above. If you are unable to clear clogged burner tube holes or if the burners or Crossover tubes are showing signs of extreme rust damage, it may be time to replace them.

Scrape The Lower Firebox

Use a narrow putty knife to scrape the sides and bottom of the lower firebox below the burner tubes. Push the debris into the tray in the bottom of the grill. Use a compressed air duster to remove debris from any hard-to-reach spots.

Brush Inside The Lid

Use a grill brush or wad of aluminum foil to remove any flaking material inside the grill lid. These flakes are carbonized grease that builds up during grill and eventually flakes off. It is not rust, paint or the porcelain enamel finish coming off.

Reinstall The Flavorizer Bars & Cooking Grates

With everything inside the firebox cleaned, it’s time to reinstall the Flavorizer bars and cooking grates. You may wish to reinstall the Flavorizer bars in a different order so they wear out more evenly, swapping center bars for edge bars or whatever makes sense to you based on how you use your grill.

Clean The Bottom Tray & Drip Pan

The shape and size of the bottom tray varies by grill model. Some are narrow and porcelain enamel coated like the one shown here. Some are made of stainless steel. On older grills like Genesis 1000, the bottom tray serves as the entire bottom of the grill box. The point is that your bottom tray may look quite different from the one shown here.

Remove the bottom tray from the grill. Use a putty knife to scrape the tray contents into a garbage bag, then use paper towels to remove any leftover grease. Remove and discard the foil drip pan liner and use paper towels to remove any liquid grease that made its way past the liner. Remove any bracket that holds the drip pan and wipe with paper towels to remove major debris and grease.

Wash the bottom tray, drip pan and bracket in hot, soapy water. Dry the parts thoroughly. Reassemble the pan and bracket with the tray, install a new foil drip pan liner, and reinstall the tray under the grill.

Clean The Work Surfaces

If your grill has stainless steel work surfaces, clean them using a good quality stainless cleaner like Weiman Stainless Steel Cleaner or Sheila Shine. See Cleaning Stainless Steel for a detailed discussion of this topic.

If your grill has plastic work surfaces, clean them with Simple Green or Purple Power. If stained, try using a scrubber sponge with these cleaners or a Mr. Clean Magic Eraser. Use ArmorAll protectant to give the surface a shiny, like-new appearance.

If your grill has wooden work surfaces, basic cleaning can be accomplished by brushing with warm, soapy water then rinsing and drying thoroughly. Extensive staining requires sanding and refinishing the surface.

Clean The Outside Of The Lid

If your grill has a stainless steel lid, clean it using a good quality stainless cleaner like Weiman Stainless Steel Cleaner or Sheila Shine. See Cleaning Stainless Steel for a detailed discussion of this topic.

If your grill has a porcelain enamel coated lid, use Simple Green or Purple Power to remove grime. To deep clean the lid, use 0000 super-fine steel wool with these cleaners, scrubbing gently to restore the original shiny enamel finish. Wipe residue with a damp cloth and dry thoroughly. See Cleaning Porcelain Enamel With Steel Wool for details and photos of the process.

Clean The Control Knobs & Panel

The burner control knobs and panel on your grill may vary from the one shown here, but the cleaning process is the same. Remove the knobs by pulling them away from the control panel. Clean the knobs and the panel using Windex or Simple Green, then replace the knobs.

Ordering Replacement Parts

As you go through the deep cleaning process, examine the condition of each part. If you need replacement parts, many can be ordered from Amazon.com which helps support this blog. However, some specialized parts may have to be ordered direct from Weber.com at 800-446-1071 or from online sources like eReplacementParts.com or GrillStuff.com.

How To Remove Odors From Cast Iron Skillets & Cookware

Does your cast iron skillet smell funky? If so, try this tip from America’s Test Kitchen. Place it in a 400°F grill or oven for about 10 minutes. This burns off the oxidized fatty acids left behind from cooking that cause the odor.

Cast iron skillets

Let the pan cool until still warm but safe to handle. Apply a thin coat of vegetable oil to the pan, removing any excess with paper towels. Your skillet is ready to go!

This method works for all cast iron skillets, pots, Dutch ovens, griddles and bakeware.

Burn Off Grates Before Grilling, Not After

There are two, maybe three reasons why it’s best to burn-off the grates in your gas grill before grilling, not after:

1) You preheat the grill and burn-off the grates in a single step, saving time and fuel.

2) There’s zero chance of forgetfulness. If you burn-off after cooking, you go into the house and enjoy your meal, only to realize 30 minutes later that your grill is glowing cherry-red-hot out on the patio. In fact, on one occasion, I left the house to run errands with my Weber Summit 450 burning-off in the backyard. I’ll never make that mistake again.

3) Leaving carbonized debris on raw cast iron grates between uses may help prevent rusting.
