How to Clean Weber Genesis Grill in Easy Steps?

How to clean the grates?

There are several ways to clean the grates of your Weber grill including:

1. Burn off method

The burn-off method is perhaps the easiest way to clean the grates of your Weber grill.

  1. After you’ve finished grilling, fire up your burners on high heat, and close the lid.
  2. Wait for roughly 15 minutes before using a grill brush to brush the grates clean.

2. Clean with hot soapy water

You can either clean with hot soapy water after the burn-off method or without performing the burn-off method first.

  1. Start by lightly scrubbing your grates with a grill brush.
  2. Soak the grates in soapy water for 45 minutes to an hour.
  3. Remove the grates from the soapy water, rinse well with clean water, and reinstall them back on the grill.
  4. Start the grill, and scrub off any excess debris and residue off the grill grates.

3. Vinegar or grill spray

You can also use household vinegar to clean your grill grates. Simply make a spray by mixing two cups of vinegar and two cups of water.

Spray the grill grates with the spray mixture, and let it sit for 15 minutes. After 10 minutes have passed, use the grill brush to remove the food particles from the grates. No rinsing is required.

Weber recommends using the company’s specially formulated grill cleaner spray to clean the grates of the grill. Follow the manufacturer’s instructions on the label.

How to clean the burners and burner tubes?

Cleaning the burner and burner tubes is an important part of Weber grill maintenance, so that they can provide strong, even heat, and also for better longevity.

You don’t have to clean the burner and burners as often as the grill grates, but should perform this task every six months or so.

The two main areas of the burners that you need to clean are the portholes and air shutter screens on the ends of the burners.

You can use a stainless steel bristle grill brush to brush the outside of the burners, and the top of the burner portholes.

If your Weber grill burner has electrodes attached to them, you need to carefully brush across them, or else you could cause damage to the ignition electrodes.

To clean the shutter screens, head to the underside of the control panel, and undo the access to the air shutters. Use a soft bristle brush to clean the air shutter screens on each of the burners.

You can find more instructions on how to clean the shutter screens in your owner’s guide of your Weber grill. Do not use the same cleaning brush for the grates and burner tubes, because doing so may transfer grease and residue across surfaces.

How do you clean the flavor bars on a Weber grill?

To clean the flavorizer bars of your Weber grill, let the grill cool completely, and then use a scraper to scrape the flavorizer bars.

Take note that flavorizer bars can rust over time due to exposure to high heat and food drippings, but you don’t have to replace them unless they have cracks or holes in them.

How to clean bottom trays?

The bottom trays can get pretty dirty from the grease that may have dripped on them, and the food particles that may have accumulated.

You can clean the bottom trays with soapy water and a damp soft cloth. If there’s any grease on them, you can soak the trays in warm, soapy water for an hour, and then rinse, and air dry.

How to clean the outside of a Weber Grill?

You can wipe down the outside of your Weber grill with warm soapy water and a soft cloth. Next, rinse the areas with clean water, and dry thoroughly. Adding to this, you may want to apply a stainless steel cleaner weekly to prevent surface rust.

How to Deep Clean Your Weber Genesis Grill?

You should deep clean your Weber grill every six months to keep it in top condition. If it’s a gas Weber grill, you first need to disconnect the gas supply from your grill.

It is a good practice to wear a pair of gloves to protect your hands from grill grease and cleaning products.

  1. You can use regular dish soap to deep clean your Weber grill. Mix 20 percent dish soap and 80 percent water in a spray bottle.
  2. Spray this mixture generously in the inside of the upper cook box, and let it sit for a few minutes. Brush it thoroughly with a stainless steel brush to remove the grease and food particles.
  3. Next, remove the grill grates, and clean them using the directions mentioned above.
  4. Clean the burners, burner tubes, and flavorizer bars.
  5. Check and test the igniters one at a time to ensure they’re in good working order or replace them if necessary. Using a soft bristle brush, remove any dirt and debris from the igniters.
  6. Using a shop vacuum, blow the dirt off the lower cook box, and reinstall the cooking grates.
  7. Remove the grease tray and catch pan, dump out the debris into your garbage can, and wipe both clean with a grill cleaner. Now, put them back in the respective slots.
  8. Lastly, wipe down the outside of your grill.

Can I Power Wash My Weber grill?

Power washing your grill is actually a quick and effective way to drive out grime from hard to clean areas.

Power Wash Weber Grill

You can either use a gas power washer or electric power washer for this task. To get started disconnect the gas supply or electrical supply of your grill from the source.

  1. Remove the propane tank or clear the power cords from the area.
  2. To prevent all the dirt and gunk from flying around, move the grill to the middle of your yard or driveway.
  3. Remove the grill grates and clean them separately.
  4. Close the grill, and soak it up with a degreaser detergent such as Dawn dish soap platinum. Add a few drops of Dawn to a bucket of water, and use a sponge to lather your grill.
  5. Attach a 15-degree or 25-degree nozzle, and rinse your grill with your pressure washer, starting from the top down.
  6. Open the grill’s lid, and let it dry completely under the sun.

How Often Should You Clean Your Weber Grill?

Using the cleaning processes mentioned above, I recommend cleaning your Weber grill grates after or before each use.

You can clean the interior of your Weber grill every three months, and wipe down the exterior once a month. Thorough or deep cleaning should be done every six months, especially if you’re a regular griller.
