How to Clean Weber Grill Grates

Tips and techniques for cleaning your Weber grill grates and keeping them clean between uses.
Includes information on gas and charcoal grill maintenance. .

Keeping the grates clean ensures that your Weber grill will always be ready to cook whenever you are.

Clean Every Time You Cook

Preheat the Grill

Preheat the grill before cooking to burn off any debris or food residue that might be stuck from the last time you cooked and to sanitize the grates.

If you have a gas model, turn all of the burners to high. Close the lid and allow the grill to preheat for 15 minutes, or until the temperature gauge reads between 500 - 600 degrees Fahrenheit. Light the coals in a Weber charcoal grill. Close the grill and open the air vents. Let the grill preheat for 15 minutes.

Scrape the Grill Grates

Use a stainless steel grill brush to remove any debris that does not fall off the grates. Go over the grates with the brush thoroughly until no debris is visible.


Keep your grill brush in good condition, and do not use it if the bristles are worn.


If you don't have a grill brush handy, crumple a sheet of aluminum foil and use long-handled tongs to scrape the grates with it.

Oil the Food, Not the Grates

Use a pastry brush to coat foods with a high smoke point oil, such as safflower or light olive oil, rather than oiling the grates. The thin film of oil will prevent foods from sticking.


  • Don't use extra virgin olive oil for grilling. Its smoke point is much lower than light or refined olive oil.
  • Oiling hot grill grates could cause a flare-up.

Scrape the Grates

After you are finished cooking, scrape the grates while they are still hot. This will dislodge any food debris that has stuck to the grill, making cleaning easier.

Deep Clean

At least twice per year -- at the beginning and end of grilling season -- perform a deep cleaning on your Weber grill grates. This will get rid of any accumulated dust or dirt, and prepare your grill to sit unused for several months.


Only deep clean the grates when the grill is completely cool.

Remove the grates from the grill and wipe them down with a solution of hot water and mild dish soap. Rinse and let the grates dry completely before putting them back on the grill.

If your grates have greasy buildup, soak them overnight in a solution of 1/2 cup dishwashing liquid per gallon of hot water. Scrub them to remove any remaining debris,then rinse and dry.

Protect the Grill

Protect your Weber grill from the elements. Store it inside a shed or garage when not in use. If you don't have space available to store your grill indoors, use a grill cover.


Never use a charcoal grill inside a garage or shed. Charcoal produces carbon monoxide as it burns, which can be deadly if not properly vented.
