Restoration · Seasoning · Cooking Tips

1
Stripping Old Seasoning
A
Spray with Easy-Off (yellow cap, heavy duty) — coat the entire pan generously. This is lye-based and dissolves old seasoning.
B
Place in a heavy-duty garbage bag and tie it shut. The bag keeps the lye moist so it can work. Leave for 2–3 days in a garage or outdoors.
C
Wearing gloves, remove pan and scrub under hot water with steel wool or a stiff brush. Repeat if stubborn buildup remains.
D
Rinse bag out before throwing in the trash. Rinse the sink with plenty of hot water — safe for stainless steel sinks and plastic plumbing.
Always wear gloves when handling lye. It will irritate bare skin.
2
Sanding (Optional — For a Smooth Finish)
A
Start with 120 grit sandpaper to level out rough texture and any remaining residue.
B
Move to 150 grit to refine the surface.
C
Finish with 220 grit for a smooth cooking surface.
D
Wash and dry immediately. Bare iron rusts fast — place on a hot burner for 1 minute to evaporate all moisture.
💡 Sanding creates a smoother cooking surface but is not required. Easy-Off alone gets you to bare iron, ready for seasoning.

Choose Your Oil

Oil Smoke Point Oven Temp Notes
Avocado oil ~520°F 450–500°F Best all-around. Highest smoke point, very durable seasoning.
Canola / vegetable oil ~400°F 400–425°F Cheap and works well. Slightly lower temp needed.
Crisco (shortening) ~360°F 400°F Classic choice. Easy to apply. Solid at room temp.
Flaxseed oil ~225°F 450–500°F Creates a hard finish but can flake over time. Expensive.
A
Preheat the oven to the temperature listed for your oil (see table above). The pan goes in hot — do not start with a cold oven.
B
Put a small amount of oil on a lint-free cloth or paper towel — about ½ teaspoon is plenty. Rub it over the entire pan — inside, outside, and handle. A little goes a very long way. (Cheap paper towels can shed lint that gets baked in — a cut-up old t-shirt works great.)
C
Now wipe it ALL off with a clean lint-free cloth or paper towel. Keep wiping until the pan looks almost dry. You're not "building up" oil — the nearly invisible residue left behind is all that polymerizes. Too much oil = sticky, gummy seasoning.
D
Place upside down in the preheated oven. Put foil on the rack below to catch any drips. Bake for 1 hour.
E
Let it cool in the oven. Don't remove it early. Once cool enough to handle, apply another coat (steps B–D) and repeat 3–4 times total. Each round adds a thin, hard layer.
💡 The technique is: rub a tiny amount over every surface, then wipe it all away. The pan should look almost dry — barely any sheen. What's left behind is the perfect amount. If it looks oily, keep wiping.
If your seasoning turns out sticky or tacky, you used too much oil. Do another round with an even thinner coat — wipe harder.

Cooking Tips — Preventing Sticking

Oil Amount

Use 1–2 tablespoons — enough to coat the entire surface. For plant-based meats, use the higher end.

Preheat First

Heat the pan, then add oil. Wait until the oil shimmers before adding food. Not hot enough = sticking.

Don't Touch It

Let ground meat sit 2–3 minutes undisturbed. A crust will form and the food will release on its own.

Don't Overcrowd

Too much food drops the temp and causes steaming, not searing. Cook in batches if needed.

💡 Beyond Meat & Impossible contain starches and binders that make them extra sticky. Use more oil, more patience, and a splash of water or broth to deglaze if needed.

Daily Care — Do's & Don'ts

✓ Do

  • Clean while still warm with hot water and a stiff brush or chain mail scrubber
  • Dry thoroughly on a hot burner after washing
  • Apply a thin wipe of oil after drying
  • Cook with it often — regular use is the best seasoning
  • Use metal spatulas — they won't hurt it

✗ Don't

  • Soak in water or leave wet — it will rust
  • Put in the dishwasher
  • Use too much oil when seasoning — thin coats only
  • Cook acidic foods (tomatoes, vinegar) for long periods on new seasoning
  • Panic about small imperfections — just keep cooking
