Cast Iron Seasoning Oil

Bare cast iron is porous and rusts on contact with water and air. A thin coat of oil heated past its smoke point polymerizes into a hard layer, the seasoning, which blocks rust and gets more nonstick with use.

You can, but many cooking oils don't polymerize fully and leave a sticky, rancid-smelling surface. This blend uses food-grade oils chosen for a high smoke point and good polymerization, plus food-grade beeswax, for a drier, tougher layer that's easier to apply thin.

A thin wipe after every wash and stovetop dry is everyday maintenance. Do a full oven seasoning when the pan looks dull or gray, shows rust spots, or food starts sticking.

Applicator, kit, and audience. Spray or pump (spray makes thin coats easy), whether to bundle a pan scraper and chainmail scrubber, and camp cooking or home kitchens, since the packaging looks fully different. Cookware brands often use it as an in-box gift or add-on.

Free samples ship in 3–5 days. MOQ is 500 bottles, and production is scheduled once packaging and labels are approved.

Wash and dry the pan, heat it on the stove to drive off moisture, apply a very thin coat, then wipe it with a clean paper towel until it looks almost dry. Bake upside down at 450–500°F for an hour, then let it cool in the oven. Repeat two or three times.

Scrub the rust off with steel wool down to gray metal, wash, dry it on the stove right away, and do two or three oven seasonings.

Too much oil. The excess doesn't fully polymerize and stays tacky. Wipe until the pan looks nearly dry before baking, and rebake a sticky pan at high heat to fix it.

Not the enamel interior; just wash it normally. You can wipe a little on exposed cast-iron rims to prevent rust.

No. It's for cast iron and carbon steel; clean nonstick per its instructions.

Store sealed and cool; if it smells rancid after opening, don't use it.

Yes. Carbon steel is seasoned the same way as cast iron.

Wash, dry, heat, then oil—every time. Rinse out food with hot water and a brush, towel it off, and set the pan over low heat until every trace of moisture is gone. While it's still warm, rub in a thin coat of CleenU Cast Iron Seasoning Oil and wipe it back until the surface looks almost dry. Leftover water is what starts rust, so don't skip the heat-dry step.

Pick an oil that cures into a hard, dry film instead of staying tacky. Plenty of kitchen oils work, but some cure unevenly and leave a sticky or rancid-smelling surface. CleenU's oil pairs food-grade oils with food-grade beeswax so a thin coat cures dry; whatever you use, apply it thin and bake it above its smoke point.

Plan on two to three oven rounds for a fresh base layer. Each round is one very thin coat, wiped back, then baked upside down at 450–500°F for about an hour and left to cool in the oven. Several thin layers build a tougher finish than one thick coat, which tends to turn sticky.

Oil blend, fill size (200 mL spray, pump, and more), packaging style, label design and language, and seasoning kits with a pan scraper, chainmail scrubber, and handle cover.

Season a new pan and a stripped, previously rusty pan two or three times each, and record seasoning color, tackiness, how eggs release, and any rust after a week. That tells you more than a before-and-after photo.
