How to Keep Your Grill Grates Clean Without Losing Your Seasoning

Want clean grates without scrubbing away that perfect seasoning? Learn how to clean your grill the right way—keeping it non-stick, rust-free, and ready for flawless BBQ every time.

Clean, But Seasoned

If you love grilling, you know how important it is to keep your grill grates clean. But scrubbing them down to bare metal after every cook? That’s a fast track to rust, sticking, and losing the flavorful seasoning that makes every sear better than the last.

There’s a better way—one that keeps your grates clean without stripping them down. Whether you’re working with cast iron, stainless steel, or porcelain-coated grates, this guide will show you how to keep them in perfect shape for flawless grilling every time.

Step 1: Clean While the Grill Is Still Warm

The best time to clean is right after cooking—while the grates are still warm, but not blazing hot.

• Burn off leftover food for 5–10 minutes with the lid closed
• Then brush gently to remove debris without scrubbing off the seasoning

Best Tools:

• Wire-free grill brush
• Wooden scraper
• Nylon brush (only after grates have cooled slightly)

Step 2: Avoid Soaking or Dish Soap

Soaking your grates in water or using harsh dish soap removes built-up seasoning and protective oils—especially on cast iron or carbon steel.

Instead:

• Spot-clean with a damp cloth
• Use vinegar spray or lemon juice + water for a natural degreaser
• Avoid scouring pads or steel wool unless you’re doing a full restoration

Step 3: Re-Season After Every Few Cooks

Just like a cast iron skillet, your grill grates develop a non-stick, protective layer when they’re oiled and heated regularly. If you over-clean or strip them down, you’ll need to re-season.

How to Re-Season:

1. Brush off any food debris
2. Wipe grates lightly with high smoke point oil (canola, grapeseed, avocado)
3. Heat the grill for 15–20 minutes until oil bakes into the metal

Pro Tip: Don’t use olive oil—it has a low smoke point and can go rancid.

Step 4: Protect Between Cooks

Keep your grates in great shape between uses by:

• Covering your grill to prevent moisture and rust
• Using a grill mat or foil liner during messy cooks
• Giving your grates a quick oil wipe after cleaning

Grate Material Matters

When to Deep Clean

If grease is caking up or you notice a funky smell during preheat, it’s time for a deeper clean. Use a mild degreaser or a grill cleaning spray and re-season afterward.

Final Thoughts

Clean grates are essential—but seasoned grates are magical. With just a few quick habits, you can keep your grill grates clean, slick, and ready to deliver perfect sears without the mess or frustration.

Protect your grates. Respect your seasoning. Your meat (and your taste buds) will thank you.
