A rusted flat top grill is frustrating, but don’t worry—it can be restored!

With a few simple steps, you can clean your griddle and prevent rust from coming back.

Understanding Rust on Flat Top Grills

Rust happens when iron or steel meets oxygen and moisture.

Over time, this corrosion damages the surface and affects your grill’s performance.

Rust is removable, and with proper care, you can prevent it from forming again.

Causes of Rust on Flat Top Grills

Several factors contribute to rust formation, including:

• Moisture exposure: Humidity, rain, or improper cleaning can lead to rust.

• Lack of maintenance: Even well-seasoned griddles rust if not properly maintained.

• Burned-on food and chemical reactions: Food debris can cause rust buildup if left on the grill for too long.

Removing Rust from Your Flat Top Grill

Follow these steps to bring your grill back to life:

• Scrape the griddle: Use a metal scraper to remove debris, gunk, and loose rust.

• Use a grill stone: This tool removes burnt-on food and surface rust quickly.

Re-Seasoning Your Flat Top Grill

Seasoning protects your griddle from rust and creates a non-stick surface. 

Follow these steps:

• Apply a thin layer of oil after cleaning.

• Use high-heat oil like flaxseed, canola, or a griddle seasoning blend.

• Heat the grill until the oil smokes, then let it cool.

Preventing Rust on Your Flat Top Grill

Rust prevention is easier than rust removal. 

Keep your grill rust-free with these tips:
