How to Clean a Grill With Household Items

Grills and outdoor cooking equipment need to be washed down, too.

It's important to learn how to clean a grill to stop food from sticking and prevent grill flare-ups. Grills inevitably get dirty from cooking on them and if sitting around waiting to be used. It's good to know both quick cleaning methods—for when you're in the middle of cooking—and how to deep clean a grill between uses (or seasons). But there's no need to turn to chemical grill cleaners. Follow this guide for cleaning your grill with household items.

Considerations Before You Get Started

While these grill-cleaning methods should work on both gas and charcoal grills, we recommend checking your manufacturer's manual to be sure. (You don't want to damage the cooking surface.) Try the easiest, least harmful cleaning method first before working your way to the more involved techniques. This could save you some time and effort.

How Often to Clean a Grill

Clean your grill after each use to avoid stuck-on food. You can quickly clean the grill grates and cooking surface, leaving it ready for the next backyard barbecue. Then, at least once a year, give your grill a deep clean. Depending on how often you use your grill, you may need to deep clean it every few months.

If you don't clean your grill, it can collect food and, therefore, bacteria buildup. Food that gets stuck inside your grill or on the grates can also burn and catch fire. Not cleaning your grill can also cross-contamination if you are cooking foods like fresh meat.

How to Clean a Grill With Onions

Onions are one of the easiest ways to clean a grill—and they're totally safe to use. There are no harsh chemicals. You might even have left over onion from the veggies you were grilling. Rather than throwing them out, put that food waste to good use.

What You Need

  • Stainless steel grill brush (optional)
  • Onion
  • Grill fork

Step 1: Heat Grill

If not already hot, turn on the grill and get it piping hot. This helps loosen debris and remelt stuck-on BBQ sauce, making it easier to scrub off.

Step 2: Scrub Grill

Once the grill is hot, reach for your trusty stainless steel grill brush and scrub the grates. If you want to avoid the potentially dangerous bristles from getting into food, grab an onion instead.

Step 3: Rub With Onion

Cut the onion in half, and using a grill fork, rub the onion cut-side-down on the grates to remove stuck-on residue. Because this grill-cleaning method may impart some onion flavor to the grates, reserve it for when grilling savory dishes rather than when grilling fruit, like peaches, for dessert.

How to Clean a Grill With Aluminum Foil

If you're grilling packets of fish or wrapping up corn, you likely already have a box of aluminum foil next to your grill. You can use this foil to clean the grates when you're done grilling.

What You Need

Step 1: Make an Aluminum Ball

When it's time to clean the grill grates, tear off a piece of foil and roll it into a ball. The crinkles are better able to scrape crusted food off the grill grates than if you were to use a flat piece of aluminum foil.

Step 2: Scrub Grill

Hold the aluminum foil ball with tongs and rub it over the grates to knock off any debris and cooked-on food. You may want to rinse the grill surface clean to avoid leaving aluminum foil behind, which can contaminate food.

How to Clean a Grill With Coffee

You can use coffee for everything from scrubbing your skin to scrubbing your grill. The good news is that you can use any kind of coffee to clean your grill, so you can save the fancy stuff for sipping. For a deeper cleaning (and if you aren't worried about removing any "seasoning" on grill grates that has built up over time), turn to the coffee-cleaning hack. Here's how it works.

What You Need

  • Pot of coffee
  • Large bucket or container (to hold the grill grates)
  • Towel

Step 1: Brew Coffee

Brew a pot of coffee. Pour the coffee into a large bucket or container.

Step 2: Remove and Soak Grill Grates

Remove the grates from the grill. (Only do this after the grates have cooled down.) Submerge the grill grates in the coffee. Let them sit for one hour. The acid in the coffee will help break down stuck-on sauce and grease.

Step 3: Rinse and Dry

Thoroughly rinse the grill grates to remove the coffee. Dry the grates before replacing them.

How to Clean a Grill With Dish Soap

Dish soap doesn't just work on your dishware. You can also use it to clean your grill. It's safe to use; after all, you already use it on other items off which you eat.

What You Need

Step 1: Heat the Grill

Fire up the grill so that it's hot. This will help loosen stuck-on food bits and sauce.

Step 2: Scrub the Grates

Using a grill brush, scrub the grates. You can also dip the brush into a container of soapy water. The steam created by the water will help remove stubborn residue.

Step 3: Cool the Grill

Turn the grill off and let it cool down. If it's a gas grill, disconnect the propane tank from the grill.

Step 4: Wash the Grates

Once the grill has cooled, remove the grill grates and burner shields (if it's a gas grill). Dunk them in a bucket filled with warm, soapy water. Scrub them with a grill brush, then rinse with a hose.

Step 5: Clean the Drip Pan

If your grill has a drip pan (aka a grease tray) or grease cup, disconnect it from underneath the grill and empty it. Then, wash it in soapy water and rinse thoroughly.

Step 6: Clear the Cook Box

Place a bucket underneath the grill to catch debris. Wearing gloves, clear out the cook box (if your grill has one) and push the debris out so it lands in the bucket below.

Step 7: Scrub the Grill Lid

Give the inside of the grill lid a quick scrub with the grill brush, then wipe with a damp paper towel. If you see what looks like peeling paint on the underside of the lid, it's a harmless buildup of carbon that can be scrubbed away.

Step 8: Reassemble and Season the Grill

Replace the burner shields and grill grates. To reseason the grates and prevent food from sticking, apply vegetable oil to the grates using a paper towel.

Step 9: Clean the Grill Exterior

If you have a stainless steel grill, apply some stainless steel polish to a microfiber cloth and buff it onto the surface, working in the direction of the grain. For ceramic or painted steel grills, wash the exterior with soapy water.

How to Keep Your Grill Clean Longer

To help your grill stay clean, use a grill cover. If you're not planning to use your grill for a few months (e.g., during the winter months), invest in a durable, waterproof grill cover that prevents rust and protects it from the elements.

Also, clean your grill tools. It's just as important to wash and clean your grill tools. Keeping the grill brush, tongs, and other grilling supplies clean will avoid spreading food debris and other dirt onto the grill grates.

Frequently Asked Questions

  • What other household products can you clean a grill with?

    You can clean your grill with other types of household products, as well. For example, beer can help break down the oil and grease on a grill. Like onions, lemons can also scrub a grill clean. The acidity of the lemon can help cut through the dirt and grime.

  • Do you need to clean a brand new grill?

    It's advisable to clean a brand-new grill before you use it. Some manufacturers apply protective coatings or oils to prevent the grill from rusting during storage and shipping. By cleaning the grill before the first use, you can remove any of these coatings. Cleaning can also ensure that you get rid of any debris, dust, or residue on the grill from storage or shipping.

  • Can you use household cleaners to clean a grill?

    You have options when it comes to cleaning your grill. Do your best to avoid harsh cleaning products, which can leave behind residue or damage the surface of the grill. First, try everyday pantry and household items, like lemon and vinegar, which are safer to use (and cheaper if you already have them in the house).
