Blackstone griddles are built to resist wear and tear to survive the longest. If you live in an area where it is normally humid, is next to the sea, or if you don’t clean your griddle on a regular basis, rust may be a problem for Blackstone griddles. As they often corrode and turn a reddish-brown color.

Are you wondering “Why is my Blackstone rusting? How can I prevent it and clean it when it happens?”

Blackstone griddles are prone to rust due to exposure to moisture and lack of proper maintenance. The combination of humidity and neglect can lead to rust formation on your griddle’s surface. To prevent this, ensure you clean and reseason your Blackstone after every use, keep it covered when not in use, and store it in a dry place. Taking these steps will help protect your griddle from rust and keep it in pristine condition for years to come.

Why And How Does Rust Form On Blackstone Griddle

A griddle made of iron is the most likely to rust. Rust is the red oxide formed when iron reacts with water or oxygen. Rust is a common, often irreversible, metal corrosion.

Rust, a reddish-brown compound known as iron oxide, forms when iron reacts with oxygen and moisture in the presence of an electrolyte like saltwater.

Griddles, such as those made by Blackstone, are primarily constructed from steel, which is an alloy composed mainly of iron and carbon.

Steel’s composition makes it susceptible to rust as it readily undergoes oxidation and corrosion when exposed to moisture and oxygen.

Therefore, when Blackstone griddles are left exposed to environmental factors, such as humidity, rain, and salt-laden air (common in coastal areas), the steel surfaces become prone to rust formation.

It’s essential to acknowledge the inherent rust susceptibility of steel and take measures to safeguard and maintain griddles to ensure their longevity and optimal performance.

If the Griddle has come to the end of its life, you will start to notice rust accumulating. Note that this is rust, which is mostly the result of your griddle getting very old.

7 Reasons Why Is My Blackstone Rusting

Rust formation on griddles is a common issue and can be attributed to several factors:

1. Moisture

The primary catalyst for rust formation is moisture. Even a small amount of water on the griddle’s surface, whether from rain, humidity, or dew, can trigger the corrosion process.

Griddles are particularly susceptible to moisture-related rust due to their exposure to the elements. Moisture is quite literally the lifeblood of rust. When water comes into contact with your griddle, it reacts with the iron, kick-starting a process called oxidation — this is what we see as rust.

Moisture may come from a variety of sources, including washing your griddle, rain, or even the steam from cooking. 

2. Air

The air we breathe contains oxygen, and as mentioned earlier, oxygen is a key component in the rusting process. So, as long as your griddle is exposed to the open air, it’s susceptible to rust formation.

3. Temperature Fluctuations

Temperature fluctuations can play a significant role in causing rust on a Blackstone griddle. Here’s how it happens:

  1. Condensation: When a warm griddle is exposed to a sudden drop in temperature, such as when evening sets in or when it rains after grilling, the metal cools down. This cooling can cause moisture in the air to condense on the griddle’s surface. Condensation provides the perfect environment for rust to develop as it introduces water to the metal.
  2. Thermal Expansion and Contraction: Metals expand when heated and contract when cooled. Repeated expansion and contraction due to temperature fluctuations can create small cracks or imperfections in the seasoning layer of the griddle. These cracks become vulnerable points for moisture to penetrate, leading to rust formation.
  3. Differential Rates: Different materials, like the metal of the griddle and its surrounding environment, can have varying rates of temperature change. This can create stress on the griddle’s surface, potentially compromising its protective layer and making it more susceptible to rust.

4. Salt Exposure:

For those living in coastal areas, or for anyone using their griddles near the sea, salt in the air can be a significant factor in rust formation.

The salt in the air, especially in the form of saltwater mist, can promote rust on metal surfaces more quickly than in non-coastal environments.

5. Use Of Acidic Food On Griddle

The acidity in certain foods, like tomatoes and citrus fruits, can contribute to rust formation on Blackstone griddles. Here’s how:

  1. Acidic Foods: Tomatoes, lemons, vinegar, and other acidic ingredients are common components of various recipes. When these foods come into contact with the griddle’s surface, their acidity reacts with the iron, causing a chemical reaction that leads to corrosion.
  2. Iron Oxidation: The acidic nature of these foods accelerates the oxidation of iron present on the griddle’s surface. This oxidation process forms iron oxide, commonly known as rust, which can compromise the griddle’s integrity.

6. Keeping your grill in the kitchen

keeping your grill in the kitchen can expose it to moisture, steam, and other factors that may lead to rust formation. Here’s why:

Steam and Moisture: Cooking in the kitchen generates steam and moisture, which can be released into the air. This humidity can settle on the grill’s surface and, over time, contribute to rust.

7. Improper Cleaning

Ever wonder why a rusting Blackstone griddle keeps seeming to rust no matter what you do? Well, the answer might be as simple as your cleaning routine.

That’s right! How often and how thoroughly you clean your griddle can play a major role in rust prevention. 

Cleaning after every use: 

A greasy griddle screams ‘welcome’ to rust. By just wiping away excess oil and food debris after each use, you can drastically reduce the chances of rust forming.

The less time oil and food particles have to break down and react with the griddle’s surface, the less likely you’ll encounter your unwanted rusty visitor. 

Gather Supplies to Clean Rust Off Blackstone Griddle

To start, gather everything you need to get the rust off of the Blackstone griddle.

A metal scraper or Blackstone cleaning brick

-Cooking oil

-Paper towels

-Grill stones or sandpaper or steel wool

Heat-resistant gloves

-Paper Towels or griddle clothing rags

The oil you are using must be cooking oil. Sesame oil, palm oil, olive oil, etc. are examples of cooking oils that can be used. Regarding rags, clothing rags are often considered the best choice. Paper towels work as well.

Make sure gloves are heatproof because resistance to heat is needed when using them on a heated griddle.

How to Get Rust Off Blackstone?

Cooking your meal on a rusty griddle is risky and one thing is for sure: it certainly isn’t appealing! Nobody likes a rusty kitchen appliance, as it can be unsightly.

The rust on the griddle surface can cause the food to stick and ruin the flavor of the dish. Follow the below steps on how to clean a Blackstone griddle that has rust.

Step 1: Safety Precautions

Begin the rust removal process by ensuring your griddle is cool to the touch to avoid any burns or injuries.

Step 2: Prepare the Griddle

Put on a pair of sturdy heat-resistant gloves for protection. Turn on the griddle to high heat and let it sit for 20 minutes. This softens the rust for easier removal. You can then turn off the griddle & allow it to cool. The rust will not instantly harden, but It’s best to clean the rust while it’s still soft.

Step 3: Removing the Rust

To remove rust from your griddle surface, you will need to use a metal scraper. While the rust is still soft and has not dried out, scrape the flat top surface of the griddle with a metal scraper.

The rust will start to come off easily. Repeat this process until you are sure that your metal griddle feels smooth when rubbed with a scraper and you can’t see any more corrosion.

Step 4: Cleaning with a Grill Stone

For a deeper clean, utilize a grill stone. Ensure the grill stone is rough on one side and lightweight with a handle for ease of use.

No soap is necessary. Drizzle 3-4 tablespoons of cooking oil over the griddle’s surface and scrub with the grill stone in slow, gentle circular motions.

Alternatively, steel wool or medium grit wet-or-dry sandpaper can be used. Wipe the griddle with a cloth, paper towels, or griddle rags. Repeat the oil scrubbing process until no rust remains.

You can also use the pumice stone to sand the griddle surface.

After thoroughly cleaning the residue off, add another 3-4 tablespoons of oil and scrub with a cloth until the oil starts coming off like it is clean. Continue cleaning off rust from the griddle with oil until there are no traces of rust left behind.

Scrubbing a griddle surface with an abrasive scrubber after every use will only damage your griddle plate. So only use these scrubbers and stones when you need to remove rust. To clean griddle, use water and a Scouring Pad instead.

Step 5: Season the Blackstone griddle

As a final step, season the griddle once it is clean and rust-free. To prevent future rust, it’s crucial to season the griddle.

This process creates a protective, non-stick coating that enhances flavor and durability.

The seasoning process creates a protective coating on top of the griddle, which acts as a non-stick surface. This ensures that your food will taste the way it was meant to be tasted.

If done correctly, this coating prevents food from sticking to the surface and makes clean-up much easier.

A seasoned griddle is easy to clean and does not corrode, which means it lasts longer and has better durability.

How To Season Your Blackstone Griddle

To season your griddle, you will need:

  • Heat resistant gloves
  • Vegetable cooking oil
  • Griddle seasoning or cast iron conditioner
  •  2 Squeeze bottles
  • Paper towel or griddle rags
  • Tongs
  • Water

Once you have removed the rust from the griddle, it’s time to reseason it with the same process used for seasoning a new griddle.

1. To season your griddle, preheat it for 10-15 minutes until the surface becomes super dark and looks almost burnt.

A squeeze bottle is ideal for helping you manage both water and oil.

Wipe the griddle’s surface with a damp paper towel to remove any loose dust or dirt.

2. Now turn off the griddle and apply a thin layer of cooking oil to the griddle surface. You can use any type of cooking oil you want.

If you have a higher quality one, like flax or olive oil, that’s great! These types of oils will bind better to the metal surface.

3. Now turn the heat up again and let it smoke. That’s all you need to do. Let the oil burn in high heat to create a bond between the metal and the oil.

4. After about 30 minutes, the amount of smoke in the air will be minimal and you know it is time to turn off the griddle.

High heat will break down the oil and the fatty acids bind together to form a new layer of molecules.

This layer helps protect the griddle surface from the outside environment and acts as a barrier to moisture. Hence helps to prevent the Blackstone griddle from rusting.

Make sure to season the griddle sides too. It’s important for easier cleaning and preventing rust.

As you cook more on your seasoned griddle with oil, the better it will get. Not only does it enhance the flavor of food, but it also provides a good cooking experience.

Step 6: Apply an Additional Layer of Oil

Drizzle another 3-4 tablespoons of cooking oil onto the griddle’s surface to create a robust protective layer against rust formation.

A thicker layer makes it more challenging for moisture to reach the iron surface.

Consider using Cast Iron Conditioner to season the Blackstone griddle, as recommended by Blackstone.
