A well-seasoned carbon-steel wok is one of the most useful tools in any kitchen — whether you run a holiday rental in Crete, manage a hotel kitchen in Athens, or simply cook at home. The video above from School of Wok walks through the cleaning process visually; this article breaks it down into clear, repeatable steps so your wok stays non-stick and rust-free no matter how often it gets used.
Why Seasoning Matters (and What Can Destroy It)
The dark, almost lacquer-like surface of a seasoned carbon-steel wok is not dirt — it is polymerized oil built up over dozens of cooking sessions. This layer is what makes the wok naturally non-stick and imparts that characteristic depth of flavour known as wok hei. Strip it away and you are back to square one: raw, rust-prone steel.
Heat, abrasive scrubbing, and prolonged contact with soapy water are the three main threats. Understanding what damages seasoning is the first step toward protecting it.
The Soap-or-No-Soap Debate
The traditional rule says never use soap on a wok. Modern dish soap is far milder than the lye-based soaps of the past, so a tiny drop used quickly will not instantly destroy a thick, well-established seasoning. That said, there is almost never a need for it. Hot water and a soft brush handle the vast majority of wok cleaning tasks faster and more safely than soap ever could.
If your wok is new or lightly seasoned, skip soap entirely until the patina has built up over several months of regular cooking. For a wok in daily commercial use — in a rental property or hotel — hot-water cleaning after every use is the professional standard.
How to Clean Your Wok After Every Use
- 1
Rinse with hot water while the wok is still warm
Immediately after cooking, while the wok is still hot but not screaming, pour hot water into it. The residual heat loosens food particles without any scrubbing effort. Swirl the water around and tip it out. Never plunge a very hot wok into cold water — the thermal shock can warp the steel.

Use a soft brush or bamboo scrubber to remove stuck food
For anything that clings on, a soft-bristle wok brush or a bamboo scrubber is all you need. Work in circular motions from the centre outward. Avoid steel wool, abrasive sponges, or scouring pads — these scratch through seasoning layers that took weeks to build. If food is really stubborn, add a splash of water and heat the wok briefly on the stove to loosen it.

Dry the wok completely on the hob
Water is the enemy of bare carbon steel. After rinsing, place the wok over a medium flame for one to two minutes until all moisture has visibly evaporated and the surface looks uniformly dry. This step alone prevents the rust spots that surprise so many wok owners who leave the pan to drip-dry.

Apply a thin layer of oil before storing
While the wok is still warm (not searing hot), add half a teaspoon of a neutral high-smoke-point oil — sunflower, rapeseed, or rice bran all work well. Use a folded paper towel held with tongs to rub the oil evenly over the entire interior surface. The goal is a film so thin it barely looks oiled. Too much oil becomes sticky and gummy with repeated sessions.
- 5
Store in a dry place with the lid off or ajar
Trapped moisture is the most common cause of rust between uses. Store your wok in a cupboard or on a rack with good air circulation, never sealed in a damp environment. In humid coastal kitchens — common across Greek islands — this step is especially important. A wok hook above the hob is ideal: it keeps the pan dry and ready.

FAQ
- Can I put a carbon-steel wok in the dishwasher?
- No. A dishwasher will strip every layer of seasoning in a single cycle and leave the steel vulnerable to rust within hours. Always wash a carbon-steel wok by hand using the hot-water method.
- My wok has developed rust spots. Is it ruined?
- Not at all. Scrub the rust off with a steel wool pad or fine-grit sandpaper, rinse thoroughly, dry completely on the hob, then re-season the wok from scratch by heating it with a thin coat of oil until it smokes. Repeat this three to four times and the wok will be back in service.
- How often should I re-season a wok used in a rental property or hotel?
- With daily heavy use, a full re-seasoning session every three to six months keeps the surface in peak condition. Between sessions, the oil-after-every-wash routine described above is sufficient maintenance.
