How do you remove commercial seasoning from a skillet?

You remove commercial seasoning by scrubbing the cooking surface with hot water, a scouring pad and a mild abrasive until the factory coating is gone and bare metal shows. Then dry the pan completely and build your own seasoning in thin oil layers.

Factory seasoning is a baked oil coating applied before the pan ships. It is thin, even and bonded to the metal, so it does not flake off in sheets the way a worn home seasoning can. That means removal is a scrubbing job, not a peeling job, and it takes patience rather than force.

What commercial seasoning actually is

Most manufacturers spray or wipe a thin layer of oil onto the raw iron or steel, then bake it at high heat until the oil polymerizes into a hard, dark film. The result is a uniform coating that resists rust during shipping and gives the pan a head start on being nonstick. It is not paint and it is not a chemical sealant, so it responds to the same things that strip a home seasoning: hot water, abrasion and strong degreasers.

Because the factory coat is applied evenly and cured hard, it can be more stubborn than a seasoning you built up yourself over months of cooking. Expect to work at it. The good news is that cast iron and carbon steel are solid metal all the way through, so scrubbing the surface cannot ruin the pan. You are only removing a film.

If your pan is a modern nonstick electric skillet with a ceramic or PTFE coating, stop here. Those surfaces are not seasoned metal and should never be scoured. The picks compared in Best Electric Skillets for Family Meals and Oven Finishing all use applied nonstick coatings rather than bare seasoned metal, so the stripping method below does not apply to them.

Stripping the factory coating step by step

Start with the hottest water your tap delivers and a stiff nylon brush or a stainless scouring pad. Scrub the entire cooking surface in small circles, rinsing often. Much of a light factory coat will come away at this stage. If the water beads and the surface still looks uniformly dark and slick, keep going.

For a coating that holds on, switch to a mild abrasive. A paste of baking soda and water, or a powdered cleanser, gives the scrub some bite without gouging the metal. Apply it with the scouring pad, work it into the surface, and rinse. Repeat until you see gray or silver metal instead of an even dark sheen. On a cast iron pan the bare metal will look lighter and slightly rougher than the seasoned areas.

Heavy factory coats sometimes need a stronger approach. A lye based oven cleaner left on the surface for a period, or a soak in a strong vinegar solution, will break down polymerized oil. Follow the product label exactly, wear gloves, and work in a ventilated space. Never combine lye and acid, and never leave a bare iron pan wet for long, because it will flash rust within minutes.

Drying and reseasoning the bare pan

Once the metal is bare, dry it immediately and thoroughly. Towel it, then set it on a warm burner or in a low oven for a few minutes to drive off every trace of moisture. Bare iron rusts fast, so do not let it sit damp on a rack while you do something else.

Reseason with a thin coat of a high smoke point oil, wiped on and then wiped off again so only a sheen remains. Heat the pan until the oil smokes, let it cool, and repeat. Three to five thin layers build a durable coat. Thick layers turn sticky and gummy, so thin is the rule.

For reference on how a manufacturer describes a factory applied cooking surface, the Presto 06857 16-Inch Electric Foldaway Skillet lists a PFAS-free nonstick surface inside and out, and the Hamilton Beach Large Electric Skillet With Lid describes a Durathon ceramic nonstick surface that it states will not crack or peel. Those are applied coatings on electric pans, not seasoned iron, and they are cleaned rather than stripped.

When stripping is worth doing

Strip a factory coat if it is flaking, if food sticks across the whole surface, or if you simply want to control what is on your pan. A patchy factory coat that has worn through in the center is a common reason to start over, because a new even layer of home seasoning performs better than a half worn factory film.

Do not strip a pan that is working well. If eggs slide and the surface looks even, the coating is doing its job. Scrubbing it off only costs you the head start the maker gave you. Judge by performance, not by color.

If you are choosing between electric pans rather than restoring iron, the published figures help you compare sizes. The Presto 06857 measures 12.5 inches wide, 20 inches deep and 8 inches tall and weighs 8.55 pounds. The Hamilton Beach Large Electric Skillet With Lid measures 20.5 inches wide, 12.5 inches deep and 7.5 inches tall and weighs 8.5 pounds. The Elite Gourmet 12 inch Ceralast PFAS-Free Ceramic Electric Skillet measures 12.2 inches wide, 17.3 inches deep and 6.3 inches tall and weighs 6.26 pounds.

Cleaning coated electric skillets instead

Coated electric skillets are cleaned, not stripped. Remove the heat control probe first, then wash the pan with warm water and a soft cloth. The Elite Gourmet 12 inch Ceralast PFAS-Free Ceramic Electric Skillet is described as dishwasher safe and fully immersible once the temperature control probe is removed, with a thick cast aluminum body that the maker states resists rusting or warping.

The All-Clad Electrics Stainless Steel and Nonstick Surface Skillet is described as having a cooking insert that is safe in an oven or broiler up to 600 degrees Fahrenheit and in a dishwasher, with plugs and cords excluded. The Blue Diamond 7QT Diamond Ceramic Nonstick 5-in-1 Electric Skillet describes a PFAS-free ceramic nonstick coating that the maker states cleans with a rinse and wipe. None of these surfaces should see a scouring pad.

For a seasoned iron pan, the sequence is always the same: strip, dry, oil thin, heat, repeat. Once the new coat is built, cook on it and let it darken with use. The makers of the electric skillets above do not publish reseasoning instructions, because their pans do not need seasoning.
