Tools You’ll Need

• Scraper (heavy-duty, preferably)
• Grill Brick (or pumice stone)
• Paper Towels
• Oil (Avocado oil works well, but any cooking oil will do)
• I used the Blackstone Cleaning Kit in my video below

Step 1: Heat the Griddle

Before you start scraping, turn your griddle to high heat and let it sit for about 20 minutes. The heat will loosen the rust, making it easier to remove. Wear heat-resistant gloves for safety.

Step 2: Scrape Off the Rust

Once the griddle is hot, use your scraper to remove as much rust and debris as possible. Scrape systematically, gathering the debris in one spot, then discard it. If the rust is severe, you might need to repeat this step.

Step 3: Scrub with a Grill Brick

After scraping, squirt 2 to 4 TBSN of oil onto the griddle and scrub it with a grill brick or pumice stone. This will smooth out the surface and remove any remaining rust or uneven spots. Use firm consistent pressure, don't be afraid to put some elbow grease in there.

Step 4: Wipe It Clean

Use paper towels to wipe down the griddle. This step may take several rounds, as you’ll need to remove all the dirty oil, debris, and loosened rust. Add more oil and keep wiping until the surface is clean and free of black residue.

Step 5: Season the Griddle

Now that your griddle is clean, it’s time to reseason it to protect the surface and create a non-stick layer.

1. Turn the griddle to medium-high heat and let it preheat.
2. Apply oil to the surface:
   • 1 tablespoon for 2-burner griddles
   • 2-3 tablespoons for 4-burner griddles
3. Use paper towels to spread the oil evenly over the surface, creating a thin layer. Be sure to coat all areas, including the corners and edges.
4. Allow the oil to burn off completely. You’ll know it’s done when the smoke stops (this takes about 15-20 minutes).
5. Repeat this process three more times, applying a thin layer of oil and burning it off each time.
