Understanding Rust on Your Blackstone Griddle
Before we dive into the repair process, it helps to understand why your griddle rusts. Blackstone griddles are typically made from rolled steel, which is prone to rust when exposed to moisture and oxygen. The seasoning layer acts as a protective barrier, much like paint on metal.
When this seasoning layer is compromised—through harsh cleaning, scratching, or simply insufficient protection—the bare steel is exposed. This exposure, combined with humidity, rain, or even morning dew, creates the perfect conditions for rust to form. Understanding this helps reinforce the importance of proper seasoning and care.
Light Surface Rust vs. Deep Pitting
Not all rust is created equal. It’s important to assess the severity of the rust on your griddle before you start. This will help you choose the right approach and materials. Light Surface Rust: This is often a reddish-orange film that appears on the surface. It’s usually easy to remove and hasn’t deeply corroded the metal. You might see this after a single rain shower or if the griddle wasn’t dried properly after cleaning. Deep Pitting/Corrosion: This indicates rust that has eaten into the steel, creating small pits or rough, flaky areas. This type of rust requires more aggressive treatment and might leave minor imperfections even after removal. While more challenging, it’s still fixable.
Essential Tools and Materials for Rust Removal
Having the right tools on hand makes the job much smoother and more effective. Before you begin, gather these items.
- Heavy-Duty Metal Scraper: Essential for removing loose debris and the initial layer of rust.
- Grill Bricks or Pumice Stones: Excellent for abrasive rust removal without scratching the griddle too deeply.
- Steel Wool or Heavy-Duty Scouring Pads: For tougher rust spots.
- Sandpaper (various grits, 60-120): For very stubborn, pitted rust areas. Use sparingly.
- White Vinegar: A natural, acidic rust dissolver.
- High-Smoke Point Cooking Oil: Flaxseed oil, avocado oil, grapeseed oil, or Blackstone’s own griddle seasoning/conditioner are ideal for re-seasoning.
- Paper Towels or Clean Rags: For wiping, cleaning, and oil application.
- Heat-Resistant Gloves: For safety when working with a hot griddle.
- Safety Glasses: To protect your eyes from rust flakes and cleaning solutions.
- Water and Dish Soap: For a final clean.
- Spray Bottle: Handy for applying vinegar or water.
Step-by-Step Guide: how to fix rusted blackstone Now, let’s get down to business. Follow these steps carefully to restore your griddle. Remember to prioritize safety throughout the process.
Step 1: Initial Scrape and Debris Removal
Start with a cold griddle. Use your heavy-duty metal scraper to remove any loose rust flakes, charred food bits, or other debris. Apply firm, even pressure. Angle the scraper to prevent digging into the griddle surface.
Scrape everything into the grease trap. This initial step clears the way for more targeted rust removal.
Step 2: Apply Rust Dissolver
For effective rust removal, a rust-dissolving agent is key. White vinegar is a fantastic, natural option.
Spray or pour a generous amount of white vinegar directly onto the rusted areas. Let it sit for 10-15 minutes. The acid in the vinegar will begin to break down the rust. For very heavy rust, you might see it bubbling slightly.
Step 3: Aggressive Rust Scrubbing
This is where the elbow grease comes in. While the vinegar is working, put on your safety glasses and heat-resistant gloves.
Grab your grill brick, pumice stone, or steel wool. Start scrubbing the rusted areas in circular motions or back and forth. Apply significant pressure. You’ll see the rust turning into a dark slurry. Continue scrubbing until the rust is visibly gone and you see bare, shiny metal or a clean, dark surface.
For deeply pitted areas, you might need to carefully use 60 or 80-grit sandpaper. Work in small sections and only where absolutely necessary. Progress to finer grits (100-120) to smooth the surface. Be gentle, as sandpaper can remove a lot of material quickly.
Step 4: Rinse and Clean the Griddle
Once the rust is removed, it’s time to clean the griddle thoroughly.
Spray the griddle with water to rinse away the rust slurry and vinegar residue. Use your scraper to push the dirty water into the grease trap. Repeat this process until the water runs clear. A small amount of dish soap and warm water can be used for a final wash to ensure all residue is gone, but make sure to rinse very well.
It’s crucial that no rust particles or cleaning agents remain on the surface.
Step 5: Dry Immediately and Thoroughly
After rinsing, drying is the most critical step to prevent immediate re-rusting.
Turn on your Blackstone griddle to medium-high heat. Use paper towels or clean rags to wipe down the surface. As the griddle heats up, any remaining moisture will evaporate quickly. Continue wiping until the surface is completely dry. You should see steam rising as the water evaporates.
A perfectly dry surface is essential before moving to re-seasoning. Even a tiny bit of moisture can cause flash rust.
Re-seasoning for Protection and Performance
Re-seasoning is paramount after you how to fix rusted blackstone. This process creates a new, non-stick, and rust-preventative layer. Don’t skip this step!
Choosing the Right Seasoning Oil
Select a high-smoke point cooking oil. Options include:
- Flaxseed Oil: Often recommended for its strong polymerization, creating a durable layer.
- Avocado Oil: Very high smoke point, great for seasoning.
- Grapeseed Oil: Another excellent choice with a high smoke point.
- Blackstone Griddle Seasoning & Conditioner: Formulated specifically for their griddles.
Avoid oils with low smoke points like olive oil or butter, as they can burn and create a sticky mess.
The Re-seasoning Process
This process involves applying thin layers of oil and heating the griddle to polymerize the oil into a hard, non-stick surface.
- Heat the Griddle: Turn your griddle to high heat and let it get very hot.
- Apply First Thin Layer of Oil: Once hot, turn off the burners or lower them to medium-low. Apply a very thin, even layer of your chosen oil to the entire griddle surface using a paper towel. Think “barely there.” Too much oil will result in a sticky, gummy surface.
- Wipe Off Excess: Use a clean, dry paper towel to wipe off all visible excess oil. You should feel like you’ve wiped it all off, but a microscopic layer will remain.
- Heat to Smoke Point: Turn the heat back to high. Let the griddle heat until the oil starts to smoke heavily and the surface turns dark. This is the oil polymerizing. This usually takes 10-15 minutes.
- Repeat: Once it stops smoking, repeat steps 2-4 at least 3-5 more times. The more layers, the better the seasoning. The griddle surface should progressively darken and become slick.
A well-seasoned griddle will have a dark, glossy, non-stick finish. This protective layer is your best defense against future rust.
Preventing Future Rust on Your Blackstone
Prevention is always easier than repair. Once you’ve gone through the effort to how to fix rusted Blackstone, you’ll want to ensure it doesn’t happen again.
Clean After Every Use
Immediately after cooking, while the griddle is still warm (but not scorching hot), scrape off any food residue. Squirt some water on the surface to deglaze and loosen stuck-on bits, then scrape into the grease trap.
Avoid using harsh detergents or abrasive scrubbers that can strip the seasoning. A soft scraper and water are usually sufficient.
Apply a Protective Oil Layer
After cleaning and drying, apply a very thin layer of high-smoke point cooking oil to the entire griddle surface. This adds an extra layer of protection against moisture.
Wipe it on, then wipe off any excess. It should look slightly shiny, not greasy.
Proper Storage and Covering
This is critical for outdoor griddles.
- Use a Griddle Cover: Invest in a good quality, weather-resistant cover specifically designed for your Blackstone. Ensure it fits snugly.
- Store in a Dry Location: If possible, store your griddle under a patio cover or in a garage, especially during prolonged periods of rain or high humidity.
- Avoid Condensation: Be mindful of temperature fluctuations, which can cause condensation under covers. Occasionally lift the cover to allow air circulation.
Avoid Harsh Cleaners
Harsh soaps or chemical cleaners can strip away the precious seasoning layer, leaving the bare metal vulnerable to rust. Stick to water and a scraper for daily cleaning.
Frequently Asked Questions About Fixing Blackstone Rust
Can I use steel wool or sandpaper on my Blackstone griddle?
Yes, for stubborn rust or deeply pitted areas, steel wool (like Brillo pads without soap) or fine-grit sandpaper (60-120 grit) can be effective. However, use them sparingly and with caution. They are abrasive and can remove the seasoning and even some metal. Always follow up with thorough cleaning and re-seasoning.
What kind of oil is best for re-seasoning after rust removal?
High-smoke point oils are best. Flaxseed oil is highly recommended for creating a durable seasoning, but avocado oil, grapeseed oil, or Blackstone’s proprietary griddle seasoning/conditioner are also excellent choices. Avoid olive oil or butter for seasoning.
How often should I re-season my griddle after fixing rust?
After fixing rust, you should immediately perform a full re-seasoning with at least 3-5 layers of oil. After that, if you maintain your griddle properly by cleaning and applying a light oil coat after each use, a full re-seasoning might only be needed once or twice a year, or if you notice new rust spots or food sticking.
Is it safe to cook on a griddle that has rusted?
No, it is generally not safe to cook on a rusted griddle. While a tiny speck of surface rust might not cause immediate harm, ingesting rust particles is not healthy. More importantly, rust severely affects the non-stick properties and even heat distribution of your griddle. Always remove all rust and properly re-season before cooking.
My griddle keeps rusting even after I fix it. What am I doing wrong?
Persistent rust usually points to issues with either inadequate seasoning or improper storage. Ensure you are applying enough thin layers of oil during seasoning and that the griddle is completely dry. Also, verify your griddle cover is effective and that it’s stored in the driest possible location, protected from rain, dew, and high humidity.
