A Blackstone griddle rewards you with crispy smash burgers, restaurant-style hibachi, and weekend pancakes for a crowd — but only if you keep the cooking surface clean. The good news: cleaning a Blackstone takes about five minutes, and once you learn the routine, it becomes second nature.
The catch most articles get wrong? You should not scrub your griddle with dish soap after every cook, and you should never take sandpaper or steel wool to it for routine cleaning. Both strip away the seasoning — the slick black layer that makes the griddle non-stick and rust-proof. Below is the method Blackstone itself recommends, plus how to handle rust, deep cleans, and the mistakes that send people back to square one.
The Quick Answer
To clean a Blackstone griddle after cooking: let it cool to below 300°F, scrape food debris toward the grease trap with a metal scraper, wipe with a paper towel, splash on a little water to lift stuck-on bits, scrape and dry it completely, then rub a thin coat of oil over the surface to protect the seasoning. Save soap for the very first clean or an occasional deep clean — never for everyday use.
What You’ll Need
You don’t need much, and you probably already own most of it.
| Tool | What it’s for |
|---|---|
| Metal scraper or sturdy spatula | Pushing food and grease into the trap |
| Paper towels or a lint-free cloth | Wiping the surface |
| Squirt bottle of water | Steam-lifting stuck-on residue |
| Coarse / kosher salt | A gentle natural abrasive for tough spots |
| High-smoke-point oil | Reseasoning after each clean |
| Heat-resistant gloves | Protecting your hands on a warm surface |
| Mild dish soap (deep cleans only) | Removing factory coating or rancid buildup |
Skip the harsh degreasers, scouring powders, and wire wheels for daily cleaning. They feel productive but quietly destroy the seasoning you’ve worked to build.
How to Clean a Blackstone Griddle After Each Use
This is the routine you’ll do 95% of the time. Do it while the griddle is still warm — cleaning is far easier before grease cools and hardens.
- Let it cool down. Bring the griddle below about 300°F — warm enough that water sizzles gently, not so hot it flashes off instantly or burns you. This is the sweet spot for cleaning.
- Scrape the surface. Use your metal scraper to push all the food bits, crumbs, and grease into the grease trap. Work in straight passes across the whole top.
- Wipe it down. Run a folded paper towel (held with tongs or a gloved hand) over the surface to pick up loosened debris and excess oil.
- Add a little water for stuck-on food. Splash a small amount of water onto the warm surface — Blackstone recommends no more than about two tablespoons at a time per section. The water steams and loosens residue. Scrape it toward the trap, then wipe.
- For really stubborn spots, reach for salt — not steel wool. Sprinkle coarse salt on the trouble area, scrub with a balled-up paper towel, then wipe clean. Salt is abrasive enough to lift gunk but won’t gouge the seasoning.
- Dry it completely. Any leftover moisture invites rust. Wipe until the surface is bone dry, or briefly turn the heat back on to flash off water.
- Re-oil to “season” it for storage. Pour a small amount of high-smoke-point oil onto the surface and spread a thin film over the entire top with a paper towel. This is what people mean by “seasoning after every use” — it’s just a protective oil coat, not a full reseasoning.
That’s it. Five minutes, and your griddle is ready for next time.
How to Clean and Season a Brand-New Blackstone Griddle
A new griddle ships with a food-safe factory coating that protects the bare steel in transit. You need to remove it before your first cook — and this is the one and only time soap belongs on your griddle.
- Wash the entire cooking surface with warm water and a few drops of mild dish soap, using a non-abrasive sponge.
- Rinse thoroughly with clean water to remove all soap residue.
- Dry completely with paper towels — don’t let it air-dry, as standing water can flash-rust bare steel.
- Season it: Turn the burners to high. Once the surface darkens, apply a very thin coat of oil, let it smoke and bake until it stops smoking, then wipe and repeat. Do this 3 to 5 times. Each round darkens the surface a little more.
After this initial seasoning, the steel should look dark and feel slick. From here on, plain water and oil are all you need for everyday cleaning.
How to Deep Clean a Blackstone Griddle
Even with diligent after-cook cleaning, carbonized oil builds up over time and the surface can turn sticky, flaky, or uneven. Plan a deep clean every 6–8 weeks (or after long storage, or whenever food starts sticking more than usual).
- Heat the griddle on high for 10–15 minutes to soften the gunk.
- Turn it off and let it cool to a safe working temperature.
- Scrape aggressively with your metal scraper to remove the loosened buildup.
- For a stubborn carbon layer, a griddle stone or pumice brick (used with a little oil or water) sands the surface smooth without chemicals.
- If the surface smells rancid or you’re starting fresh, you may use a little mild soap here — but only because you’ll fully reseason afterward.
- Rinse if you used soap, dry completely, then reseason 2–3 times as described above.
A deep clean essentially resets your griddle, giving you a fresh base for new seasoning layers.
How to Remove Rust from a Blackstone Griddle
Rust happens — usually from storing the griddle wet or skipping the oil coat. Don’t panic, and don’t reach for sandpaper as a first resort. Most rust comes off with this method:
- Heat the griddle to loosen rust and any old seasoning.
- While warm, scrape the rusty areas with your metal scraper.
- For light rust, scrub with coarse salt and a little oil using a balled paper towel.
- For stubborn rust, spray the area with a mix of equal parts white vinegar and water, let it sit about 15 minutes, then scrub. Steel wool is acceptable here — heavy rust removal is the one job it’s meant for.
- Wipe away all rust residue, rinse if you used vinegar, and dry completely.
- Reseason from scratch — 3 to 5 thin oil-and-heat cycles. Rust removal always strips seasoning, so reseasoning isn’t optional.
The Best Oil for Cleaning and Seasoning a Blackstone
You want a high smoke point and a neutral flavor so the oil polymerizes into a hard, non-stick layer instead of burning off or going sticky. Good choices include:
- Avocado oil — very high smoke point, neutral; a top pick.
- Canola oil — affordable, neutral, widely available.
- Flaxseed oil — bonds into a hard seasoning layer (can be brittle if applied too thick).
- Grapeseed oil — high smoke point, clean flavor.
Avoid olive oil and butter for seasoning — their low smoke points make them better for actual cooking than for building a protective layer.
Common Mistakes That Ruin a Blackstone Griddle
- Using dish soap every time. Grease-cutting soap dissolves the seasoning. Reserve it for the first clean and rare deep cleans.
- Storing it wet. The fastest route to rust. Always dry and oil before covering.
- Skipping the oil coat. That thin film is what blocks moisture and rust between cooks.
- Scrubbing with steel wool or sandpaper routinely. This is rust-removal-only territory — daily use strips you back to bare steel.
- Cleaning a cold, hardened surface. Clean while warm; grease lifts far more easily.
- Applying oil too thick. A thick coat goes gummy and sticky. Thin layers, wiped almost dry, are the goal.
How to Store Your Blackstone to Prevent Rust
Once the surface is clean, dry, and lightly oiled, cover it with a hard cover or weather-resistant griddle cover to keep out moisture, dust, and pests. If you live somewhere humid or rainy, store the unit indoors or in a garage when possible. Empty the grease trap after every use — leftover grease attracts bugs and rodents and can go rancid.
Frequently Asked Questions
What is the best way to clean a Blackstone griddle?
Heat the griddle, scrape food into the grease trap with a metal scraper, wipe with a paper towel, use a splash of water (and coarse salt for tough spots) to lift residue, dry it completely, then apply a thin coat of oil. No soap needed for everyday cleaning.
Can I use soap on a Blackstone griddle?
Only for the first clean of a new griddle or an occasional deep clean where you’ll fully reseason afterward. Grease-cutting soaps strip the seasoning, so they’re not for routine use.
How often should I clean my Blackstone griddle?
After every single use. A quick scrape, wipe, and oil coat each time keeps the surface non-stick and prevents rust. Add a full deep clean every 6–8 weeks.
Why does food stick to my Blackstone griddle?
Usually one of three things: the surface wasn’t preheated enough, there isn’t enough oil on it, or the seasoning has worn thin and needs rebuilding. Preheat fully, add a little oil before cooking, and reseason if the surface looks dull or gray.
Do I need to season my griddle after every use?
Yes — but “seasoning” here just means wiping on a thin protective coat of oil after cleaning. A full multi-layer reseasoning is only needed after deep cleans or rust removal.
Why does my griddle look dull or gray instead of black?
That’s worn or thin seasoning. Run a few thin oil-and-heat cycles to darken it back up. The more you cook and reseason, the deeper and more even the black layer becomes.
Final Thoughts
Cleaning a Blackstone griddle isn’t hard — it’s just a habit. Scrape, wipe, a splash of water, dry, and oil, every time you cook. Save the soap and the steel wool for the rare deep clean or rust rescue. Treat the seasoning as the most valuable thing on your griddle, protect it after every cook, and your Blackstone will stay slick, black, and rust-free for years of great food.
