Cast iron pans are workhorses in Greek homes, holiday rentals, and hotel kitchens — but they demand a different cleaning approach than ordinary cookware. The Epicurious video above shows the full process visually; the steps below give you a clear, repeatable routine. Follow it consistently and your pan will outlast every non-stick skillet in the cupboard.
Why Cast Iron Cleaning Is Different
Cast iron is porous iron protected by polymerised oil — the so-called seasoning layer. Harsh detergents, long soaking, and air-drying strip or rust that layer, turning a prized piece of cookware into a flaking, sticky mess. The goal of cleaning is to remove food residue without stripping the seasoning, then lock out moisture before it can cause rust.
This matters especially in coastal Greek properties where salt-laden air accelerates corrosion. A three-minute post-cook routine is all the protection you need.
What You Need Before You Start
You need a stiff-bristled brush or a chainmail scrubber, a clean cloth or paper towels, a tiny amount of neutral cooking oil (sunflower or grapeseed work well), and access to a hob. That is the entire kit — no specialist products required.
One thing to set aside: the idea that soap is always forbidden. Modern dish soap is mild enough that a small drop used occasionally will not destroy seasoning, but hot water and a brush handle 95% of cleaning jobs without soap at all.
5 Steps to a Perfectly Clean Cast Iron Pan
- 1
Cool the pan — but not all the way
Take the pan off the heat and let it rest for two to three minutes. You want it warm, not screaming hot and not stone cold. A warm pan releases food residue more easily, and thermal shock from cold water on a very hot pan can cause cracking.
- 2
Scrub with hot water and a stiff brush
Hold the warm pan under hot running water and scrub with a stiff-bristled brush or a chainmail scrubber in circular motions. For stubborn stuck-on bits, add a tablespoon of coarse salt as an abrasive and work it around the surface with the brush. The salt acts as a gentle scrub without harming the seasoning.
- 3
Rinse and check — no soap unless necessary
Rinse thoroughly under hot water. If food is fully removed, skip soap entirely. If grease or odour remains, add one small drop of mild dish soap, scrub for 20 seconds, and rinse again immediately. Never leave soapy water sitting in the pan and never submerge it in a sink full of water.
- 4
Dry completely on the hob
This step is non-negotiable. Place the pan on the hob over medium heat for one to two minutes until every trace of moisture evaporates — you will see the surface go from dull to a faint sheen as it dries. Moisture left behind is the only real enemy of cast iron; rust can appear overnight in a damp kitchen.
- 5
Apply a very thin coat of oil
While the pan is still warm, add a small drop of neutral oil and rub it across the entire interior surface — and the outside too if you have a moment — with a folded paper towel. The goal is a micro-thin film, not a puddle. Too much oil will turn sticky. Store the pan in a dry place, ideally with the lid off so air can circulate.

FAQ
- Can I put a cast iron pan in the dishwasher?
- No. The dishwasher combines prolonged soaking, high heat, and aggressive detergent — exactly the combination that strips seasoning and triggers rust in one cycle. Always hand wash.
- My pan has a patch of rust. Is it ruined?
- Not at all. Scrub the rust away with a chainmail scrubber or fine steel wool under running water, dry the pan completely on the hob, apply a generous coat of oil, and bake it upside-down in the oven at 220°C for an hour. Repeat once more if needed. The pan will be as good as new.
- How often should I re-season a cast iron pan?
- The thin oil coat applied after every wash is a form of continuous re-seasoning. A full oven re-seasoning (baking oiled pan at high heat) is only needed after rust removal, heavy stripping, or if food starts sticking regularly — typically two to four times a year for pans in regular use.
