Sticky cast iron commonly has an overly thick coating of oil that has not fully polymerized. Clean the tacky layer, dry the pan, and use a nearly invisible film when oiling it again.

Remove the tacky film

Use warm water, mild dish soap and a nonabrasive brush or scrubber. Repeat if the surface remains gummy. Do not keep spreading more oil over a sticky patch, and dry the pan thoroughly to avoid rust.

Apply much less oil

Spread a small amount of neutral cooking oil across the skillet, then buff with a cloth until the surface appears almost dry. Visible puddles and drips tend to make sticky, uneven coatings rather than strong seasoning.

Heat with care

Follow your skillet maker’s seasoning directions. Provide ventilation and use oven mitts around very hot metal. Many pans develop durable, thin seasoning through regular cooking, and a thick glossy coating is not a sign of better protection.
