Sticky cast iron after seasoning usually means the oil layer was too thick or did not fully polymerize during heating. The solution is a thinner coat and an appropriate seasoning cycle, not adding more oil on top.
What went wrong
Seasoning forms when a very thin coating of suitable cooking oil changes under heat and bonds to iron. A glossy puddle or visible drip can leave a gummy residue. Different pan colors are normal; a sticky feel is more useful information than color alone.
Clean before restarting
Wash or gently scrub the tacky residue with warm water and suitable dish soap as needed, then dry thoroughly. Avoid leaving damp cast iron sitting on the counter. If the surface remains gummy, repeat cleaning rather than simply oiling it again.
Apply an almost invisible coat
Use a small amount of neutral cooking oil, wipe the entire pan, then buff again with a clean cloth as if removing it. Follow the pan manufacturer’s seasoning temperature and oven-safety instructions; hot handles and ovens can cause severe burns.
How to prevent it next time
Avoid thick layers, skip soaking after cleaning, dry promptly and cook regularly with a moderate amount of fat. A dark-black surface is not the only acceptable appearance for a functional pan.
Frequently asked questions
Is sticky seasoning unsafe?

Can I use olive oil to season a pan?
People use different oils, but a neutral oil and a method recommended by the manufacturer are a straightforward starting point.
