A clean grill cooks better, lasts longer, and is far safer — grease buildup is the number-one cause of flare-ups and grill fires. The good news is you don't need to deep-clean after every cook. A 5-minute scrub each time, plus a deeper clean a few times a season, keeps any gas or charcoal grill in great shape. Here's the routine that works, the order to do it in, and how to handle the greasy parts most people ignore.
Step-by-step
Burn off the grates with the lid down
Before you cook (or right after), fire the grill on high with the lid closed for 10–15 minutes. The heat turns stuck-on food and grease to brittle ash that brushes off easily. On charcoal, do this while the coals are still ripping hot. This single step does most of the work for you.
Scrub the hot grates
While the grates are still hot, scrub them with a grill brush, a coil-style cleaner, or a wadded ball of foil held in tongs. Get the tops and sides of each bar. A cleaning stone or pumice block knocks off heavier, baked-on carbon that a brush leaves behind. Heat is your friend here — cold grates are far harder to clean.
Let it cool, then degrease the grates
Once the grill is warm (not hot), spray the grates with a grill-safe degreaser, let it sit a couple of minutes to break down the grease, and wipe with a cloth or paper towels. For a deeper clean, lift the grates out and scrub them in a sink or bucket of hot, soapy water, then rinse and dry.
Clean under the grates and empty the grease
This is the part that prevents fires. On a gas grill, brush off the metal heat tents/flavorizer bars, then scrape the bottom tray and slide out the grease cup — empty it and wipe it clean. On charcoal, dump the cold ash from the catcher (ash holds moisture and rusts the bowl). Never let grease pool in the bottom.
Wipe down the exterior and lid
Wipe the lid and exterior with warm soapy water or a stainless cleaner; for the inside of the lid, scrape off any flaking carbon buildup (it's baked-on smoke, not mold). A clean lid reflects heat better and keeps black flakes off your food.
Re-oil the grates and reassemble
Reinstall everything, then wipe the clean grates with a thin coat of high-smoke-point oil on a paper towel. This protects cast-iron grates from rust and keeps food from sticking next time. Fire the grill briefly to set the oil, and you're ready for the next cook.

How often should I clean my grill?
Give the grates a quick brush before and after every cook, and empty the grease cup regularly. Do a deeper clean — grates, heat tents, bottom tray, and exterior — every few weeks in grilling season or after about 10–15 cooks. A full teardown clean once or twice a year keeps a gas grill running well for a decade.
Can I clean grill grates with water and soap?
Yes. Removable grates can be scrubbed in hot, soapy water for a deeper clean — just dry them and re-oil afterward so cast iron doesn't rust. For everyday cleaning, a hot burn-off and a brush are enough; you don't need soap every time.
What's the best way to clean a grill without a wire brush?
Heat the grates and scrub with a tightly wadded ball of aluminum foil held in tongs, a coil-style (bristle-free) brush, a wooden grill scraper, or a pumice cleaning stone. Half an onion on a fork also works in a pinch. These avoid the loose-bristle risk of cheap wire brushes.
How do I get baked-on grease off my grill?
Burn it off on high first to carbonize it, then scrub. For what's left, spray a grill-safe degreaser on warm (not hot) surfaces, let it dwell a few minutes, and wipe. Heavy carbon on grates comes off with a pumice cleaning stone. Always empty the grease tray so it can't ignite.
How often should you deep-clean a grill?
Quick clean (hot grate brush and grease tray) after every cook. Deep clean (degrease, scrape interior, vacuum ash) once a season at minimum, or every 10-20 cooks for heavy users. A neglected grill cooks worse and rusts out 3-4 years earlier than a maintained one.
Best way to clean grill grates fast?
Burn off — close the lid, run all burners on high for 10-15 minutes, then brush the hot grates with a coil brush or grill stone. Most stuck-on grease burns to ash. For deeper cleaning, soak removable grates in hot water + dish soap + baking soda for an hour, then scrub.
