A well-cared-for cast iron skillet is one of the most rewarding tools in your kitchen: it gets better with age, gives great sear, and can last generations. With a little routine care and the right fixes when things go sideways, you’ll keep yours non-stick, rust-free, and guest-ready. Below are friendly, practical steps and tips from Suzie Q Cleaning to help you master cast iron skillet cleaning and maintenance.

Everyday cleaning — the simple routine

Use this after most meals when nothing is seriously stuck on:

Let it cool just enough so it’s safe to handle (don’t pour cold water on a red-hot pan).
Wipe or scrape loose food with a spatula or a wooden/china scraper.
Rinse with warm water and rub gently with a non-metal brush or sponge. No dishwasher—ever.
If needed, add a small pinch of coarse kosher salt and a little warm water, scrub with a paper towel or sponge to lift stuck bits (salt acts as a gentle abrasive).
Dry thoroughly — use a towel and then warm it briefly on the stove to evaporate any remaining moisture.
Oil lightly: Apply a very thin coat of neutral oil (canola, vegetable, or light olive oil) with a paper towel to the cooking surface. Wipe off any excess so it’s not sticky.

If food is stuck on (safe lifting techniques)

Boil a little water in the skillet for a few minutes to loosen residue.
Use a wooden or nylon scraper to remove the softened bits.
If stubborn, repeat the salt scrub method.
Rinse, dry, and oil as above.

Removing rust or heavy build-up (deep clean & recovery)

If rust appears or the seasoning is damaged, restore it:

Scrub the rust with a fine-to-medium steel wool pad or a chainmail scrubber until you see clean metal. (For heavy rust, a short white-vinegar soak — half vinegar/half water — can help; don’t soak longer than 30–60 minutes and watch it carefully.)
Rinse completely and dry immediately (stove top drying helps).
Re-season (see next section) to rebuild the protective coating.

How to season cast iron (rebuild non-stick)

Seasoning creates a durable, non-stick layer from polymerized oil. Here’s a reliable method:

Preheat your oven to 450–500°F (use a temperature your cookware can safely handle).
Clean and dry the skillet thoroughly.
Rub a thin layer of high-smoke-point oil (flaxseed, vegetable, or canola) all over the inside and outside. Wipe off all excess — the surface should look almost dry.
Place the skillet upside-down on the middle oven rack (put foil or a baking sheet on the lower rack to catch drips).
Bake for 1 hour. Turn oven off and let the skillet cool completely inside the oven.
Repeat 1–3 times for a stronger seasoning if needed.

Long-term care tips (keep it going)

Never soak cast iron — prolonged water contact causes rust.
Skip the dishwasher and harsh detergents. Mild soap sparingly is okay if you really need it, but avoid regular heavy soap.
Store dry and lightly oiled: After cleaning, ensure the skillet is fully dry and rub on a thin film of oil before storing.
Avoid acidic long-cooking (tomato, vinegar) in newly seasoned pans — once well-seasoned it’s more forgiving, but frequent acid exposure can wear seasoning.
Rotate use with other pans rather than leaving empty on the stove (reduces dust/scratches).

Quick “in-between” routine (2 minutes)

Wipe with a paper towel after cooling.
Spray a little warm water and scrub if needed.
Dry and place on low heat for 30–60 seconds.
Rub a tiny bit of oil and store.

Troubleshooting FAQ

My pan is sticky after seasoning. You used too much oil. Wipe off excess and bake once to polymerize, or strip and re-season.
How do I remove stubborn black spots? Lightly scrub with salt or a soft pad; if persistent, do a gentle re-seasoning.
Can I use soap? Occasional mild soap is fine, but avoid frequent use. Always re-oil after washing.
