How to Remove Rust from a Blackstone Griddle

Finding rust on your Blackstone griddle can be disheartening, but it is not the end of the
road. Because Blackstone griddles are made of raw, rolled steel, they are prone to
oxidation if not seasoned or stored correctly. With a little elbow grease and the right
materials, you can restore your surface to its former glory.
What You Will Need
Griddle scraper or putty knife
Heavy-duty scouring pads (stainless steel or heavy-duty synthetic)
Griddle stone (or pumice stone)
Cooking oil (vegetable, canola, or grapeseed)
Paper towels
Heat-resistant gloves
Step-by-Step Restoration

1. Heat the Surface
   Turn your griddle on to medium-high heat. Warming the metal helps loosen the rust
   and makes the cleaning process significantly easier. Let it heat for about 5–10
   minutes.
2. Scrape Away Large Rust Particles
   Using a metal griddle scraper or a heavy-duty putty knife, carefully scrape the surface
   to remove loose rust flakes and any burnt-on food residue. Be mindful to push away
   from yourself.
3. Scour the Surface
   Use a griddle stone (or a brick) with a handle, or a scouring pad. Scrub the surface in
   a circular motion, applying firm pressure. If you are using a stone, it will break down
   and mix with the oil/rust into a thick paste. Wipe this away with paper towels (use
   tongs to hold the towel to avoid burns).
4. Clean and Rinse
   Once the surface looks cleaner, turn off the heat and let the griddle cool slightly. Wipe
   the surface thoroughly with paper towels until they come away clean. You may need to
   do a final rinse with water while the griddle is still warm to remove any remaining fine
   grit, then immediately dry it thoroughly.
5. Re-Season Immediately

This is the most important step. Once clean and dry, apply a very thin layer of high-
smoke-point oil (like grapeseed or vegetable oil) to the entire surface. Heat the griddle

until the oil smokes, then wipe it off and repeat the seasoning process 2–3 times to
create a new, non-stick barrier.

Pro Tip: Always keep a thin coat of oil on your griddle after every use, even if you are
just storing it for a few days. This prevents moisture from reaching the steel and forming
new rust.
