Turn off the gas supply to the grill. You do not want to have dangerous gasses build up during the cleaning process that can lead to injury.
- Locate the gas supply valve on the propane tank for LP grills and where the grill connects to the house for LNG supplied grills.
- Turn the knob or lever clockwise to shut off the gas supply running into the grill.
- Remember "righty-tighty, lefty-loosey" to close and open valves.

Remove any metal plates or coverings over the burners and scrub clean. The plates protect the burners and help to disperse the heat to allow for even cooking.
- Clean the burner protectors by scrubbing with sponge or scouring pad dipped in soapy water.
Check the holes in the burners for clogs and use a toothpick to dislodge any objects that may be blocking the flow of gas. In some grill models the burners are easy to remove for cleaning; if yours do not come out easily, you can wipe them clean while they are in place. ^{[4]

Expert Interview. 7 January 2021.} If your grill has a removable bottom pan, you can take it out to scrape all the debris away. If the bottom pan is secured in place use a metal spatula or grill scraper to push any burnt scraps through the grease hole and catch them in a trash bag.
Once all the chunks are gone, scrub the bottom with a sponge or scouring pad and soapy water to remove any built up grease or grime. Lots of drippings and food scraps tend to build up under the burners of the grill. Pay close attention to this area and clean it as much as possible to avoid corrosion.
Use the grill scraper to gently clean any flecks off the underside of the lid and wipe it clean with a soapy sponge. Be careful not to scratch the metal or scrape any undamaged paint off the lid as this may lead to rusting or corrosion.
8
Replace burner covers and grill grates. Reassemble your grill by putting everything back in the reverse order you removed it.
- Burner covers and grill grates usually rest in place.
- Look for groves or ledges to place these items back in the proper location.
Turn the grill on high and close the lid for 15 minutes to burn off any remaining soap or cleaners you used on the interior surfaces of the grill.
10
Turn off the burners and oil the grates. Oiling the grates will help to prevent your food from sticking to the surface.
- Dip a paper towel in canola oil.
- Use tongs to rub the oily towel over the surface of the hot grates.

Make sure that the gas valve is completely closed to avoid filling the grill with dangerous flammable gas during the cleaning process.

Check the drip pan under the grill and replace as needed. Most grills have a disposal drip pan or cup. Clean the surface of the drip pan holder, and replace the liner with a fresh aluminum pie plate or tin can.
- If your drip pan is not disposable, wipe out the grease with paper towels.
- After removing as much grease as possible rinse the drip pan with a solution of soapy water.
Make a soapy solution to clean the outside of the grill with 1 teaspoon of dish soap per quart of water.

Check your gas line for leaks. Regularly inspect the gas lines connecting your grill to the gas tank by applying a small amount of soapy water to the surface of the line and connectors. This should be done each season you are using the grill and monthly during periods of high usage.
- Use a rag or brush to apply soapy water along the length of the gas line.
- Make sure to apply soapy water liberally around the connections and valves.
- Look for any bubbles that indicate gas is leaking causing a potentially dangerous situation.
4
Burn off any drippings to prevent grimy build up. In between every 3-4 times you grill, heat up the grill without any food present.
- Turn the burners on high.
- Close the lid to burn up any drippings that have fallen on the burner protectors.
- Allow the heat to build up inside the grill for 10-15 minutes.
Invest in a cover for your grill to protect it from the elements when it is not in being used. Keeping rain and debris from piling up on your grill will help keep it from rusting and extend the life of your grill.

Expert Answer

To clean sticky residue off a gas stove, use a zero-grade metal scrubber and dishwashing soap. Alternatively, professional-grade acids can be used to remove stubborn residues by applying them for 30 minutes before scrubbing them off with a metal scrubber. A butter knife can be used to remove thick hard grease, as I won’t scratch the surface.

Question

Can you run hose through your grill to clean?

Community Answer

NO! Do not do that, it will ruin your grill. Cut a lemon in half, stick it on a sharp utensil and rub it on the top of the grill of where you cook. Scrubbing the grates with a balled-up piece of aluminum foil works as well.
