How to Re-Season a Blackstone Griddle

There’s a difference between a Blackstone that needs to be re-seasoned and one that needs to be restored. Restoration handles rust — the actual orange stuff that means metal damage. Re-seasoning handles a worn, sticky, or patchy seasoning layer that’s still bonded to clean metal underneath. Most owners who think they need restoration actually need this — a 60-minute process that resets the cooktop without touching the metal.

Done right, a re-season is the difference between a Blackstone that frustrates you and one that becomes the most-used cooker in your backyard.

When you need to re-season

Signs that point to a re-season (not a restoration):

• Food has started sticking when it didn’t before
• Gray or silver patches showing through the dark seasoning
• Seasoning is flaking in places — small chips, not whole sheets
• The surface has gone from smooth to slightly tacky or sticky
• You stored the griddle covered all winter and the surface looks dull but not rusty
• You bought it used and the seasoning is uneven but no orange rust

If you see actual orange rust, jump to the restoration guide — re-seasoning over rust doesn’t work; the rust needs to come off first.

What you’ll need

• A bottle of high-smoke-point oil (8 oz is plenty)
• Heavy paper towels (10-15 sheets)
• A metal scraper (the one that came with the griddle is fine)
• Tongs (you’ll need them to handle hot paper towels)
• Heat-resistant gloves
• A few drops of dish soap or a half-cup of coarse salt (only if there’s heavy stuck-on residue)

That’s it. No sandpaper, no degreaser, no special chemicals. If the metal is still mostly clean under the seasoning, the re-season process handles everything.

The process

1. Heat the griddle to maximum, all burners. Run for 10-15 minutes with the lid open. The plate will smoke as residual oils volatilize. This step softens any old gummy seasoning and prepares the surface for scraping.

2. Scrape the entire plate while hot. Long, even strokes with the metal scraper. Loose flakes of old seasoning will come up. The goal is to remove anything that’s not bonded — solid seasoning stays, loose stuff goes. Push debris to the grease channel.

3. Wipe with a damp paper towel (held in tongs — the plate is dangerously hot). This lifts the loose debris the scraper missed. Don’t soak the surface — a damp towel, not a wet one. Wipe in long passes, replace the towel when it’s dirty.

4. For stubborn stuck-on residue: salt + damp rag. If the scrape didn’t get everything, sprinkle a half-cup of coarse salt across the trouble spots and scrub with a damp rag (in tongs). Salt is mildly abrasive but won’t strip seasoning. Wipe, repeat if needed.

5. For really stubborn cases only: one drop of dish soap on the trouble spot. This is the nuclear option. A single drop of soap, scrubbed and rinsed quickly with damp paper towels, removes residue that nothing else will. You’ll lose seasoning where you used soap — accept that, you’ll rebuild it in the next steps. Don’t soap the whole plate; only treat the affected zone.

6. Apply a very thin oil layer. A tablespoon of oil in the center, spread edge-to-edge with a folded paper towel held in tongs. The plate should look damp, not wet. This is the most-failed step — too much oil produces a sticky, gummy surface that peels in sheets. Less is more.

7. Let it smoke off completely. 5-8 minutes per pass. Wait until smoking stops before applying the next layer. Don’t rush this. The smoke is the oil polymerizing into a hard coating; interrupting that cycle is what creates flaky, peeling seasoning.

8. Repeat 3-5 times. Each pass darkens the plate further. By pass 3, you’ll see uniform black across the surface. By pass 5, the re-season is solid.

9. Cool, oil one more time, store covered. A final thin oil coat protects the seasoning until the next cook. Cover the cooker and let it rest at least 4 hours before any food contact.

How it should look afterward

A successful re-season produces a uniformly dark, slightly glossy, smooth surface. Run a finger across it cold — it should feel like glass, not like sandpaper. Slight color variations are fine; obvious patchiness means you need another pass or two.

Compare the plate to itself: every section should look about the same. If the front-right has a different color than the back-left, that section needs another oil pass.

What the first cook tells you

Cook bacon. Seriously. Don’t try eggs, don’t try pancakes, don’t try anything that demands a perfect seasoning yet. Bacon contributes fat to the seasoning, releases easily even on a marginal surface, and tells you what you’re working with.

If bacon releases cleanly: you’re done.

If bacon sticks anywhere: that section needs another oil pass after this cook is done.

If bacon sticks everywhere: the re-season didn’t fully take — repeat the process and pay closer attention to the “very thin oil layers” rule.

Maintenance after re-seasoning

The work that prevents the next re-season:

• Water-and-scrape after every cook, while the griddle is still warm
• A thin oil coat before storage, every time
• No soap, ever, on the established seasoning
• Cover the cooker after it’s fully cooled and dried (not while still warm — trapped steam ruins seasoning)
• Store somewhere protected from direct rain if at all possible

Done right, a Blackstone needs re-seasoning roughly once or twice a year — once at the start of grilling season after winter storage, optionally once midsummer if it sees heavy use.

Frequently asked questions

How is re-seasoning different from a full restoration? +

Re-seasoning works on a griddle whose metal is still healthy — the surface is dirty, sticky, or worn, but not rusted. Restoration is required when there's actual rust on bare metal. The processes are different: re-seasoning takes 60 minutes; restoration takes 2-4 hours. If you see orange anywhere, you need restoration first.

Why does my seasoning keep peeling in sheets? +

Almost always too-thick oil layers during seasoning. The oil pools, doesn't fully polymerize, and creates a brittle layer over the original. The fix is to scrape off the failed layer and re-season with thinner oil applications — the plate should look damp, not wet, after each oil pass.

Can I use butter or olive oil to re-season? +

No. Butter has milk solids that don't polymerize cleanly. Olive oil's smoke point is too low and it goes rancid faster. High-smoke-point oils (avocado, refined canola, grapeseed, flax) are the only oils that build durable seasoning.

How thin is 'very thin' for the oil layers? +

After spreading, the plate should look dull-shiny but not wet. If you can see oil pooling anywhere, it's too thick — wipe more off. The classic test: drag a clean paper towel across the surface. It should pick up just a faint sheen, not visible drag-streaks.

Do I need to re-season every spring? +

Most outdoor griddles benefit from a light re-season at the start of grilling season, especially if they sat through a wet winter. If the cooker was stored dry and indoors, you can often skip — check the surface, and only re-season if you see gray patches, stickiness, or food sticking.
