Clean and Maintain Your Grill

Whether you prefer cooking with charcoal or gas, one thing remains the same -- cleaning and maintenance is essential for great grilling.

Cleaning Gas or Charcoal Grills

Whether you prefer cooking with charcoal or gas, one thing remains the same – routine and yearly cleaning and maintenance is essential for great grilling.  A wire brush or grill stones, rags or paper towels, cooking oil and some cleaning supplies are all you'll need to make sure it’s safe and running great, every time you fire it up.

Interior Care

Step 1

Check the flame tamers. These directly cover the burners and are also called heat tents and vaporizer bars. Brush off debris with a wire brush. Do not put oil on flame tamers after cleaning.

Step 2

Tube, u-shape, flat and cast burners should be checked when flame tamers are removed. Clogged burners can lead to uneven cooking and premature burner failure. Scrub burners with a dry wire brush, giving attention to the burner port area (the jets where the gas comes out) to remove any food residue or grease.

Infrared and rotisserie burners are a little different. Ceramic burners are delicate and need to be cleaned carefully. Turn ceramic burners on for 10 minutes to burn off excess grease and food debris.  With the burner off, use tweezers to remove any large food debris.

Step 3

Routine brushing of the cooking grates with a dry wire brush or grill stone prevents food and bacteria buildup.

  • Gas Grills - Burners MUST BE OFF before cleaning! If using a grill stone, no water is required -- the stone will remove residue. After you have cleaned the cooking grates, spray them with cooking oil.
  • Charcoal Grills - Clean surfaces when the grill is still hot. Use a grill brush that dispenses water to steam-clean the grates. If your brush does not have that feature, a little water sprinkled onto the brush produces the same effect.
  • Chrome wire grates - Coat with vegetable oil after cleaning to prevent rust.
  • Cast iron grates - Coat with a vegetable oil after cleaning to prevent rust.
  • Porcelain-coated steel rods and porcelain-coated cast iron - No coating is required unless porcelain is missing. Coating prior to cooking will help prevent food from sticking.
Good to Know

If your cooking grates are damaged, using a grill brush may dislodge bristles. Replace your cooking grates. Check your grill brush to make sure that bristles are in good condition and are not coming out.

Step 4

Before you start your gas grill, take a moment to inspect the fuel line for cracks.  Monthly, perform a more thorough inspection. Brush soapy water along the connections.  If bubbles form when the gas is running, tighten your connections or replace the line.

Step 5

Clean the venturi tubes. Venturies are the tubes that mix air and gas and feed to the burners. They need to be clear to work properly. The tubes make good homes for spiders and insects during the off-season. Even a small blockage can become a fire hazard. Remove the entire burner/tube assembly and clean with soapy water. Clean the holes with a wire brush, paper clip or small piece of wire. Replace when dry and ensure the venturi tube is properly aligned with the gas valve.

Caution

Make sure the venturi is in place either by sight or with your fingers. Not having the venturi tube placed over the gas valve can be dangerous if the grill is lit.

Step 6

Check propane levels on the gauge atop the tank. If you don’t have a gauge, pour warm water down the side of the tank and follow it with your hand. The place where the water temperature starts to feel cold is your fuel level.

Step 7

Check the ignition system for a spark.  No spark?  Check that the pressure regulators are tight on the tank and you can try manual ignition using a grill lighter and maintaining a safe distance from the flame. If that works, check the batteries in your ignition switch and clean or replace the electrodes. Your owner’s manual will show you how.

Good to Know

Read and keep your instruction manual and warranty. The instruction manual will explain how to order replacement parts.

Exterior Care

Grill surfaces are made out of different materials and require different cleaning methods.

  • Porcelain-coated steel lids - are fragile and can crack or break easily, so they should be treated similar to glass. Clean with a mild dishwashing soap and water. Dry with microfiber rags or paper towels. To polish, use window cleaner.
  • Powder-coated steel lids - Clean with a mild dishwashing soap and water. Dry with microfiber towels or paper towels. Do not use stainless-steel polish on what might be a “stainless look,” as this will damage the finish.
  • Stainless-steel lids - Clean with hot soapy water first to remove any grease and grime. For stubborn, baked-on deposits or discoloring, use a sponge and scrub with the grain of the stainless-steel. (Going against the grain will damage the appearance of the grill.) Afterward, rinse with warm water to remove all soap. Then dry with a clean cloth or rag. Once the lid is dry, polish with a stainless-steel cleaner or wipe.
  • Painted lids – may be refinished using high-temperature paint. Use sandpaper and a scraper to remove any corrosion and wash the surface thoroughly with soap and water.  Once dry, paint the surface according to the manufacturer’s instructions. 

Additional Grill Maintenance Tips

  • If your grill sits on pavement, place a tarp or a grill mat underneath it to catch debris, grease and food.
  • Give your grill a thorough cleaning at least twice a year. If you grill frequently, a good rule of thumb is every 5 to 10 uses. Not cleaning a dirty grill can shorten its lifespan.
  • Never place a grill in a garage, breezeway, carport or under any flammable surface. Keep your grill at least 10 feet from the house.
  • Always store LP containers upright in a secure position and never store them in your car.
  • Keeps kids and pets away from a hot grill, just as you would a hot stove. 
  • Always light a gas grill with the lid open.
