How to Prevent Flare Ups on a Gas Grill


The big cookout is coming, and you have a few hours to get your gas grill ready for cooking. You enjoy cooking on your gas grill, but don't enjoy the occasional flare-ups of the gas flame. Flare-ups occur when liquid or food particles fall onto the gas grill's flame. You also can experience flare-ups when you first turn on the gas grill; these flare-ups are caused by a buildup of food debris on the grill's grates and lava rocks.

Things You'll Need

  • Dishwashing soap
  • Laundry detergent
  • Hot water
  • Bucket
  • Rubber gloves
  • Grill brush
  • Bucket or other container
  • Water hose
  • Clean rags or shop towels
  • Scraper
  • Trash bag
  • Cooking oil
  • Disconnect the propane tank from your gas grill. Set the tank to the side.

  • Mix 2 tablespoons of dishwashing soap, 1 tablespoon of laundry detergent and 1 gallon of hot water in a bucket. Wear rubber gloves.

  • Stir the soap mixture with a grill brush.

  • Open your gas grill's lid and remove the grill grates and the shield over the burner. Place the parts on a clean flat surface.

  • Remove the lava rocks in the bottom of the gas grill, and place them in a bucket or other container.

  • Scrub the grill grates and the shield with the grill brush and soap mixture. Scrub both sides of the grates and shield.

  • Rinse the grill grates and shield with water from a hose.

  • Dry the grill grates and shield with a clean rag or towel.

  • Scrub each lava rock gently with a clean rag or towel to break up any caked-on debris. Do not use the grill brush and do not wash the lava rocks in the soap solution or water.

    Place the scrubbed lava rocks on a clean rag or towel. Continue scrubbing the rocks until they are all clean.

  • Wipe the bottom of your gas grill with a clean rag or towel to remove any loose food debris and dirt. Use a scraper to break up any cake-on debris.

  • Place any scraped-off debris in a trash bag.

  • Place the grill's burner shield in place.

  • Place the lava rocks in the gas grill. If any of the rocks contain a large amount of caked-on debris, place the dirty side down so the dirt will burn off once you turn on the grill.

  • Place the grill grates in place.

  • Reconnect the propane tank, turn on the gas, and light the grill.

  • Let the gas grill run for 10 minutes to burn off any caked-on debris present on the lava rocks.

  • Turn off the gas grill.

  • Wet a clean rag or towel with 2 tablespoons of cooking oil.

  • Wipe the cooking oil-soaked rag or towel on to the grill grates to re-season them.

Tips & Warnings

  • To prevent flare-ups resulting from food falling into the grill, cut excess fat from your meat before placing the meat on the grill. Leave only about ¼ inch of fat on your meat. Less fat means less flare up.
