Our top picks at a glance

A clean grill cooks better, lights more reliably, lasts longer and is far less likely to flare up. The trick is to do a little often, so a deep clean never becomes a big job.

The short answer

Every cook: scrape the grates. Every few cooks: empty the grease tray. A few times a year: deep clean. Skip the loose-bristle wire brush.

After every cook (2 minutes)

  1. Burn off residue by running the grill hot for 10 to 15 minutes with the lid closed (gas or charcoal).
  2. Scrape the grates with a bristle-free scraper or brush while they are warm. Use long-handled tools and heat-resistant gloves.
  3. Wipe or lightly oil the grates if you like.

Weekly (5 minutes)

  • Empty the grease tray or drip pan. Built-up grease is the main cause of flare-ups.
  • Check the burner area for debris.

Deep clean (30 to 60 minutes, a few times a year)

  1. Let the grill cool completely. For gas, close the tank valve first.
  2. Remove the grates and soak them in hot, soapy water, then scrub and rinse.
  3. Remove the heat shields or flavorizer bars and scrape off buildup.
  4. Clean the burners. Brush the outside, and clear clogged ports with a stiff wire or burner-port tool. Look for spider webs in the tubes.
  5. Scrape the firebox and the inside of the lid. Flaking residue is mostly carbon, not paint, but scrape it off.
  6. Empty and wash the grease tray.
  7. Wipe the outside with warm soapy water. For stainless steel, wipe with the grain.
  8. Reassemble, then reconnect the gas and leak test per your manual.

Charcoal and kamado grills

  • Empty the ash before each cook, because it holds moisture and chokes airflow.
  • Clean the grates as above, and wipe down the vents.
  • For kamados, follow your maker's advice on gaskets, covers and vents to prevent mold.

Pellet grills

  • Vacuum the fire pot every cook or every few cooks, empty the grease bucket and clean the temperature probe. See pellet grill won't heat up.

About wire brushes

Loose wire bristles can break off and end up in food. Doctors and safety agencies have reported injuries from swallowed bristles. A bristle-free scraper, a nylon brush or a cleaning stone avoids the risk. If you use a wire brush, check the grates and the food afterward.

Our top picks

Clean grates without loose bristles

Bristle-free grill scrapers and brushes

Clean grates without loose wire bristles that can end up in food.

Price tier 1 of 4:Under $150

A scraper or bristle-free brush avoids loose wire bristles that can end up in food. It needs a little more effort on baked-on grime, and wood scrapers wear down.

What we like

  • Avoids loose metal bristles that can get into food
  • Works on most grate materials when used as directed
  • Cheap

Trade-offs

  • Needs more elbow grease on baked-on grime
  • Wooden scrapers wear down and need replacing
  • Check that the tool suits your grate material
Best for
Anyone who wants to keep wire bristles off the grill.
Skip it if
You already use a cleaning method you are happy with.

For heavy build-up

Grill cleaning bricks and stones

A pumice-style block for scouring flat-tops and grates.

Price tier 1 of 4:Under $150

A pumice-style block cuts through burnt-on residue on griddles and grates. It can scratch some finishes and wears away, so skip it on porcelain or non-stick grates.

What we like

  • Cuts through burnt-on residue on griddles
  • Cheap
  • No bristles

Trade-offs

  • Can scratch some finishes
  • Wears away as you use it
  • Check that your grate or top is compatible
Best for
Griddles and heavy build-up.

You have porcelain-coated or non-stick grates.

Handle warm parts safely

Heat-resistant grill gloves

Silicone or aramid gloves for handling hot grates, trays and pans.

Price tier 1 of 4:Under $150

Silicone or aramid gloves help when you move warm grates and trays. Check the temperature rating, and remember that wet gloves can conduct heat.

What we like

  • Protects hands on hot surfaces
  • Makes cleaning a warm grill easier
  • Washable

Trade-offs

  • Check the stated temperature rating and read the care label
  • Wet gloves can conduct heat

  • Measure your grill before you order
  • Cheaper fabric can fade over years

Frequently asked questions

How often should I clean my grill?

Scrape the grates after every cook while they are warm, empty the grease tray regularly, and do a deep clean a few times a year, plus a full clean before winter storage and after the first use in spring.

Are wire grill brushes safe?

Wire bristles can break off and end up in food, and doctors and safety agencies have reported injuries from swallowed bristles. A bristle-free scraper, a nylon brush or a cleaning stone avoids the risk. If you use a wire brush, inspect the grates and food afterward.

Can I clean a hot grill?

Scraping while the grill is still warm is easiest, but use a long-handled tool and heat-resistant gloves. Never spray cleaners on hot grates, and let the grill cool before a deep clean.

What do I do about a grease fire?

Turn off the gas and close the lid. Never use water on a grease fire. If it is out of control, step away and call 911.
