Cooking outside on a blackstone griddle can be adventurous and also time-consuming, but it produces a delicious feast without using a pile of dishes and utensils. A Blackstone griddle is an outdoor cooking equipment made of steel, and is popularly known for offering a versatile surface. A variety of foods such as burgers, pancakes, eggs, bacon etc. can be cooked on it.
Blackstone griddle is an ideal choice for cooking meats and getting a crispy exterior on food as it's heated using propane or natural gas, which leads to high temperatures. However, the grill is rusted when it is exposed to moisture. The great relief is that rust can be cleaned through the following guide.
Reasons for Blackstone Griddle Rust
There are certain causes that allow a Blackstone griddle to rust.
Exposed to Moisture - Griddle can be exposed to moisture if not properly dried after cleaning, causing it to rust. Additionally, living in areas with high humidity can also be the reason for rust.
Using Irregularly - The surface can begin to rust if one doesn't use their griddle on a regular basis. This occurs when the protective seasoning layer gradually degrades due to infrequent use.
Poor Storage - Leaving the griddle outside without covering it, or storing it at a place where it can easily get wet, allows rust to form. Make sure to find a safe storage spot when not using it frequently.
Damaged - If the seasoning layer is damaged with scratches for any reason, it exposes the steel underneath to moisture, which may cause rusting.
Tools Required to Clean
Here are some necessary tools one would need while cleaning the Blackstone griddle.
-
Scraper (To remove any rust )
-
Cooking oil ( Avocado oil works well, but can use any)
-
Paper Towels
-
Grill Bricks
-
Heat-resistant Gloves
Now that all the tools are handy. Here is the step-by-step guide on how to clean Blackstone griddle rust.
Step #1: Warm Up the Griddle

Step #2: Scrape Off the Dust
After the griddle is heated, use the scraper to remove as much dust and debris as possible. Clean it in a methodical way. First, gather all the debris in one place, then clear all debris. Repeat this step again if the rust is gravely widespread.
Step #3: Use a Grill Brick to Scrub
Once you are done scraping, put 2 to 4 tablespoons of oil onto the griddle and use grill brick to scrub it after being done with scraping. It will allow the surface to smoothen down and remove rest of the remaining rust. Make sure to use firm and consistent pressure without being scared to put some elbow grease on it.
Step #4: Wipe Down the Surface
This step might take various rounds of cleaning as it's required to remove all the dirty oil, debris and loosened rust. Now, use paper towels to wipe down the griddle surface. If required, keep on adding more oil and wiping it until the surface is fully cleaned and free of black residue.
Step #5: Reseason the Griddle
Now, reseason the griddle to protect the surface and create a non-stick layer.
Follow the instructions below for reseasoning.
-
Let the griddle preheat after putting it on medium heat.
-
Apply one tablespoon on the surface for 2-burner griddles and 2-3 tablespoons for 4-burner griddles.
-
Ensure to coat all areas evenly with oil, even the corners and edges, creating a thin layer using the paper towel.
-
