With Christmas gatherings just around the corner, the last thing you want is a grill that won’t light, won’t heat, or smells like burnt grease when you open the lid. Holiday grilling is all about flavor, freshness, safety — and a clean, well-maintained barbecue.

If you’ve been wondering whether your grill needs a deep clean before the Christmas rush, here are the five warning signs you should never ignore.

1. 5 Signs You Should Deep Clean Your Grill Before Christmas

If your grill hits you with a wave of burnt grease smell, that’s the clearest sign it needs a full deep clean ASAP.

Over time, grease:

• Hardens into thick layers along the firebox and burners

• Creates flare-ups that can burn food

• Produces bitter, smoky smells that ruin flavor

• Can even become a fire hazard
  

Many homeowners assume this smell is “normal.” It’s not — it’s a red flag.

2. Your Grill Isn’t Heating Up Like It Used To

If your grill used to heat up in 5–7 minutes but now takes 20+ minutes, something is wrong.

Common causes include:

• Blocked burners

• Clogged venturi tubes

• Grease blocking airflow

• A dirty heat shield

• Carbon buildup restricting gas flow
  

This issue becomes especially noticeable during the colder holiday months.

And yes… almost always, the real fix is a deep clean, not a repair.

3. You Haven’t Cleaned It Since Summer — Or Longer

By December, here’s what you’re dealing with inside:

• Rancid fats

• Carbón buildup

• Mold growth

• Insects hiding inside burners

• Broken igniters

• Rust forming under drip trays
  

A holiday deep clean isn’t cosmetic — it prevents:

• Food contamination

• Fire hazards

• Bad cooking performance

• Embarrassing smells when guests arrive

The USDA also recommends regular grill cleaning for food safety:https://www.usda.gov/about-usda/news/press-releases/2025/05/13/usda-serves-food-safety-guidelines-your-summer-cookout

4. Your Flames Look Uneven, Weak, or Yellow

A healthy grill flame should be:

• Strong

• Mostly blue

• Even across the burner
  

If your flame looks weak, yellow, patchy, or only half the burner lights up, you’re dealing with:

• Clogged burner ports

• Blocked igniters

• A grease-filled firebox

• Poor ventilation
  

This is one of the biggest signs your grill is overdue for a professional cleaning — especially before cooking for Christmas guests.

5. Food Is Sticking More Than Usual or Tasting “Off”

When your food starts sticking or tasting smoky, bitter, or “dirty,” that means:

• Grease has carbonized

• Grates have lost seasoning

• Burnt food particles are stuck under the grill lid

• Your grill is re-burning old residue
  

Christmas meals deserve fresh flavor — not last summer’s grease.

If the taste isn’t clean, your grill definitely isn’t either.

Bonus Sign: You're Hosting Christmas Dinner

If you’re planning to cook:

• Ribeye

• Tomahawk steaks

• Turkey

• Lamb chops

• Christmas ham

• BBQ sides

• Grilled vegetables

• Bacon-wrapped anything
  

…your grill needs to be performing perfectly.

Holiday guests notice:

• Smells

• Cleanliness

• Flavor

• Presentation

• Safety
  

A deep clean isn’t optional — it’s part of your holiday prep routine.

What a Professional Deep Clean Includes (So You Know What to Expect)

A true deep cleaning includes:

Full Grill Disassembly

• Burners

• Grates

• Heat plates

• Drip pan

• Firebox

• Ignition area
  

Degreasing + Carbon Removal

This is crucial before Christmas since old grease is a major fire hazard.

Burner Clearing & Realignment

Ensures even heat for your holiday meals.

Reassembly + Safety Testing

Nothing is more important than safe flames and proper ignition.

Final Polish & Ready-to-Cook Testing

Your grill should look and perform like new.

7 Common Mistakes Homeowners Make Before the Holidays

Mistake 1: Cleaning only the grates

The firebox and burners are where the real buildup hides.

Mistake 2: Using water incorrectly

Water inside burners or ignition chambers causes rust and non-lighting issues.

Mistake 3: Ignoring the drip pan

This is one of the top causes of grill fires.

Mistake 4: Closing the lid after grilling without cleaning

Trap grease = trap odors.

Mistake 5: Waiting until Christmas Eve

By then, it may be too late to fix deeper issues.
