How to Remove Rust from Grill Grates (and Keep It Off)

Restore your grill to like-new condition—no harsh chemicals needed.

Rusty grill grates are more than just an eyesore—they can ruin the flavor of your food and shorten the life of your grill. The good news? You don’t need to toss out your grates. With a few simple steps, you can remove rust and get back to grilling safely and confidently.

What Causes Rust on Grill Grates?

• Moisture – Leaving your grill uncovered or exposed to rain and humidity

• Lack of Cleaning – Grease and food particles attract moisture

• Not Seasoning the Grates – Just like a cast iron skillet, grates need a protective oil layer
  

Step-by-Step: How to Remove Rust from Grill Grates

1. Preheat and Burn Off Turn your grill on high for 15–20 minutes to burn off excess food and loosen rust.

2. Scrub with a Grill Brush or Foil Once the grates cool slightly, scrub with a stainless steel brush or a crumpled ball of aluminum foil. This removes surface rust effectively.

3. Use a Vinegar and Baking Soda Paste Mix equal parts vinegar and baking soda into a paste. Apply to the grates and let sit for 30 minutes. Scrub again with your brush or foil.

4. Rinse and Dry Thoroughly Use warm water to rinse off the mixture, then dry completely to avoid future rust buildup.

5. Season the Grates Apply a thin coat of high-heat cooking oil (like canola or avocado oil) to the grates. Turn the grill on for 15 minutes to bake in the oil and form a protective layer.

Tips to Prevent Rust

• Clean your grill after every use

• Keep your grill covered when not in use

• Re-season the grates regularly

• Schedule a professional deep clean to reset and protect your grill
