Spring Grill Startup Checklist (Get Ready for Cookout Season)

Spring is when neglected grills come back to life — and when problems show up. Here's the complete pre-season checklist that catches spider webs, dried gaskets, fuel issues, and rust before the first cook.

The first warm Saturday of spring is when most grills come back into service. It’s also when most grill problems first show up — spider webs in burner tubes, dried gaskets, low propane, surface rust, possibly small animal intrusion.

This is the complete startup checklist. Done correctly, you catch all the off-season issues before they ruin a cookout. Skipped, you’ll discover the problems mid-cook with guests waiting.

Why spring startup matters

A grill that sat covered through winter has been through:

  • Multiple freeze-thaw cycles
  • Possible moisture intrusion
  • Spider and insect activity (especially in early spring)
  • Possible rodent intrusion in some climates
  • Gasket dryness from cold and inactivity
  • Surface oxidation on bare metal

None of these are catastrophic on their own. Together, they’re why the first cook of spring is the cook most likely to have problems.

The startup checklist

Visual exterior (5 minutes)

Walk around the cooker. Note:

  • New rust spots that weren’t there in fall
  • Damaged or torn weather cover
  • Loose or missing screws on the cabinet
  • Mouse droppings or nesting material under or around the grill
  • Damaged gaskets (top of cabinet, around lid)
  • Any visible wear that needs addressing

Cover removal and airing (30 minutes — passive)

Pull the cover. Open the lid. Let the cooker air for 30 minutes minimum. Releases trapped moisture from winter storage and lets you smell anything that’s gone musty (early sign of mold).

While it’s airing, you can do other yard prep. This is hands-off time.

Firebox interior inspection (5 minutes)

Look for:

  • Mouse nests or evidence of rodent intrusion (more common in winter than people think)
  • Moisture damage or surface rust on the bottom
  • Insect activity
  • Cracked or damaged components

Address any major issues before continuing. Mouse nests need to come out before any cleaning. Rust gets wire-brushed before re-seasoning.

Venturi tube inspection (10 minutes)

This is the most-skipped step and the #1 cause of “my grill won’t work right after winter.” Spider webs accumulate in venturi tubes during late winter and early spring as spiders become active.

Pull burners, look down each venturi tube with a flashlight, clear with a venturi brush or pipe cleaner. Full procedure in Spider Webs in Your Grill Burner Tubes.

If you skip nothing else, don’t skip this.

Standard deep clean (30 minutes)

Brush grates, scrape flame tamers (or wave grates / heat plates), wipe lid interior, vacuum firebox, empty grease tray. The full procedure is in How to Deep Clean a Gas Grill.

For first-cook-of-the-season, the deep clean is more important than the regular monthly because residue has had all winter to harden.

Gasket inspection and replacement (5-15 minutes)

Check the gasket between lid and firebox. Look for:

  • Cracking, charring, or visible compression flat-to-the-cabinet
  • Detachment from the metal
  • Dryness or brittleness

If any of those are present, replace the gasket. Universal gaskets ($15-25) work on most cookers; brand-specific gaskets fit better. Replacement is a 10-minute job.

A worn gasket means the cooker can’t maintain temperature properly — the symptom shows up first under the high-heat cooks of spring.

Propane and connection check (5 minutes)

For gas grills:

  • Inspect the propane hose for cracks, especially near the regulator and tank ends
  • Verify regulator is tight on the tank
  • Check tank fill level (drop the tank from the cabinet, weigh it — empty tank weighs ~17 lbs, full ~37 lbs; difference is propane in pounds)
  • Slowly open tank valve when reconnecting (count to 10) to avoid tripping the regulator’s safety lockout

Test fire and flame check (5 minutes)

Light each burner individually:

  • Confirm clean ignition (no excessive sparking, no delayed lighting)
  • Verify blue flame color (yellow on first lighting may be dust/dryness — give 5 minutes)
  • Check flame distribution across each burner (uniform vs. patchy)
  • Verify all burners reach high heat within 5 minutes

If anything looks off after 10 minutes of running, troubleshoot before cooking real food.

After the startup, before the first cook

Final 15 minutes:

  1. Run all burners on high for 10 minutes with lid closed
  2. Brush grates one more time
  3. Lightly oil the grates with a paper towel and high-smoke-point oil
  4. Now you’re ready to cook

The 10-minute high-heat run burns off any cleaning chemical residue and brings the cooker to even temperature. The light oil gives the first food (especially fatty cuts) something to release from.

Throughout the season

The spring startup is comprehensive once-a-year work. After it, the schedule is:

  • After every cook: brush warm grates (5 min)
  • Monthly during peak season: empty grease tray, scrape flame tamers (15 min)
  • Mid-summer (optional): mid-season deep clean if grilling is heavy

The next major event is the fall winterization in October-November.

Frequently asked questions

How long does the spring startup take?

60 minutes of active work, plus 30 minutes of passive airing time. Plan a Saturday morning. Don't try to compress it — every step on the checklist exists because of a real failure mode.

Do I need to do this if my grill was stored indoors?

Most of it, yes. Even indoor-stored grills accumulate dust, may have spider webs (less common but possible), and have gaskets that aged a year. Skip the moisture-related steps; do the rest.

What if I find rust during startup?

Surface rust gets wire-brushed and re-oiled in 15 minutes. Moderate rust on grates needs the [rust restoration approach](/grill-care/how-to-clean-rusted-grill-grates). Through-rust on structural components (firebox, cabinet) is an end-of-life signal — the cooker may not be worth saving.

Can I skip the venturi tube inspection if I don't see any problems?

Skip at your own risk. Spider webs in venturi tubes are often invisible from outside the burner — the only way to verify is to pull the burner and look down the tube with a flashlight. The 10-minute inspection prevents the most common spring grill problem.

When should I do this during the year?

Late February through April depending on your climate. The right window is when temperatures are reliably above freezing but before peak grilling season starts. Doing it too early (still cold) means working in unpleasant conditions; doing it too late (peak season) means a busy weekend that's harder to dedicate.
