Why Prepping Your Grill Matters

Whether you bought your first Weber, Traeger, or an entry-level propane grill, taking time to season a new grill and remove manufacturing residues is crucial. Fresh-from-the-box grills often come with protective oils, coatings, and metal dust that shouldn’t make their way into your food. The first-time grill burn off helps eliminate these while also building a non-stick, rust-resistant surface.

Understanding how to prep a grill properly means better-tasting food, safer cooking, and a longer-lasting grill. It also builds your confidence for your first time grilling — whether you're cooking burgers, steaks, or veggies.

How to Set Up a New Grill

If you’re assembling a grill for the first time, follow the manufacturer’s instructions to the letter. This includes properly installing gas lines, propane tanks, burners, or charcoal trays. Here’s a basic checklist:

Assemble grill body and lid with all bolts and fittings tightened
Insert grill grates and heat plates
Connect propane tank or natural gas line for gas grills
Place drip pan and grease trap
Position the grill on a stable, fire-safe outdoor surface

Refer to your grill’s manual for how to start the grill, especially if you're using an electronic ignition system or a chimney starter for charcoal. Make sure everything is secure before you ignite for the first time.

How to Clean a Grill Before Use

Cleaning a grill before first use is essential to remove oils, factory grime, and dust from production and shipping. Here’s how to clean your new grill grates before seasoning:

Fill a bucket with hot, soapy water (use mild dish soap)
Place grates and any removable parts into the bucket
Scrub thoroughly with a grill brick, soft brush, or non-metal sponge
Rinse all parts with clean hot water in a second bucket
Dry immediately with a towel — don’t let cast iron air dry or it may rust

This process is the same whether you’re working on a gas or charcoal grill seasoning job. It's also a good idea to wipe down the inside of the firebox to remove dust or loose metal shavings. If you're asking "do I need to season a new grill?" — yes, after cleaning, that’s your next step.

How to Season a Grill for the First Time

Seasoning a new grill helps develop a protective layer over your grates. This prevents rust, minimizes sticking, and improves flavor over time. Here's how to season new grill grates like a pro:

After cleaning and drying, coat grates with high smoke point oil (canola, avocado, or grapeseed oil work well)
Apply oil using a spray bottle or a paper towel (never pour directly on grates)
Wipe oil evenly over the entire surface, including corners and edges
Reinsert the grates and fire up the grill
Let it run on high for 15–20 minutes or until it stops smoking

This process — often called curing a grill — helps carbonize the oil into a non-stick coating. For cast iron grates, multiple rounds may be required. If you're unsure how to season a propane grill versus charcoal, the process is the same — only the ignition method differs.

How Long to Burn Off a New Grill

Doing a new grill burn off clears factory coatings that weren’t removed during cleaning. It’s recommended even if you’ve already scrubbed. Here’s what to do:

Turn all burners to high (for gas grills)
Close the lid and allow the grill to heat for 15–30 minutes
If using charcoal, burn a full chimney of coals and allow them to ash over
Allow heat to neutralize chemical smells or leftover residue

Many people wonder how long should you let a grill burn off? The sweet spot is at least 20 minutes. Watch for the smoke to taper off — that's when it's ready. Then turn off your grill and allow it to cool before your first real cook.

Gas vs. Charcoal: First-Time Tips

Using a Gas Grill for the First Time

For those wondering how to use a gas grill for the first time, here are the basics:

Check all connections are tight — especially if using a propane tank
Open the lid before starting
Turn on the gas supply
Use the ignition button to light the grill
Set burners to your desired temperature and preheat

Using a Charcoal Grill for the First Time

For your first time using a charcoal grill, you'll need to know how to build and control the fire:

Use a chimney starter with lump charcoal or briquettes
Let coals ash over before dumping them into the grill
Spread them based on desired heat zones
Place the grill grate back and let it heat up
Close or adjust vents to manage airflow and temperature

Learning how to use a grill (gas or charcoal) comes down to control. Always monitor temperatures and preheat thoroughly before cooking.

Ongoing Grill Maintenance

After that first grill burn-in, you’ll want to keep it running like new. Here’s how to maintain grill grates and overall function:

Brush after each use: Use a grill brick or safe metal brush to remove food residue
Oil occasionally: Re-season every few cooks to prevent rust
Cover your grill: Always use a weatherproof cover to keep out moisture
Store indoors in winter: For long life, especially with charcoal grills
Inspect for rust or corrosion: Especially in burner tubes, drip pans, and lids

Routine maintenance is the key to safe grilling and great flavor. The more you use your grill, the better seasoned the grates become — just like a cast iron skillet. Check out our selection of grill cleaning products here.

FAQs About Using a New Grill

Do you have to season a new grill?

Yes. Seasoning protects the grates, reduces sticking, and helps create better sear marks and flavor over time.

How long should you let a grill heat up?

Generally 10–15 minutes. For a new grill, go 20–30 minutes to burn off residues.

What’s the best oil for seasoning a grill?

Use oils with a high smoke point like canola, peanut, or grapeseed oil. Avoid olive oil or butter.

Can I skip cleaning a new grill before use?

No. Cleaning a grill before use removes dangerous manufacturing residues and improves safety.

How do I know when the grill is ready?

Preheat until you reach your desired cooking temperature. For most gas grills, this is 400–500°F.

Should I spray grill grates before cooking?

You can apply oil before preheating, but never spray directly onto a hot grill — it can ignite. Use a paper towel or brush.

Do I need to burn off my grill every time?

No. A full burn-off is only necessary on first use or after deep cleaning. After normal use, a quick brush and wipe-down is enough.

Will rust burn off a grill?

Some surface rust can burn off, but it’s best to clean and re-season thoroughly. Avoid cooking directly on rusted surfaces.

What should I do when the grill is on fire?

Turn off the burners (if gas), close the lid, and shut off the gas supply. Do not use water on grease fires — use baking soda or a fire extinguisher.

What is the best first-time grill for beginners?

Start with a mid-range propane grill that offers temperature control, a built-in thermometer, and a solid grate system. Napoleon offer great options for starter grills.

Conclusion

From how to season a gas grill to learning how to clean grill grates before cooking, your first time using a grill sets the stage for years of delicious memories. Don’t skip the prep.
