How to Clean Cast Iron Pan: The Ultimate Guide for a Perfect Season

A well-maintained cast iron pan can last for generations, but improper cleaning can ruin its seasoning and lead to rust.

How to clean cast iron pan? and why its matters?

Cast iron pans are beloved for their durability and heat retention, but they require special care. Unlike regular cookware, harsh scrubbing or soap can damage the seasoning—the polymerized oil layer that prevents sticking. Learning how to clean a cast iron pan correctly ensures it stays rust-free and improves with each use.

Step-by-Step: How to Clean a Cast Iron Pan

1. Let It Cool (But Not Too Much)

Never plunge a hot pan into cold water—thermal shock can warp or crack it.
Wait until warm (not scalding) before cleaning.

2. Scrub with Hot Water & a Stiff Brush

Use a nylon brush or chainmail scrubber (like this popular one on Amazon) to remove food residue.
Avoid steel wool (too abrasive) and excessive soap (it can strip seasoning).

3. For Stubborn Residue, Use Coarse Salt

Sprinkle kosher salt and scrub with a damp cloth—it acts as a gentle abrasive.
Rinse thoroughly and dry immediately to prevent rust.

4. Re-Seal with a Thin Oil Coat

After drying, apply a light layer of vegetable oil, flaxseed oil, or lard.
Buff off excess with a paper towel to avoid stickiness.

Modern soaps are mild, but excessive use can weaken seasoning over time.

❌ Soaking or Dishwasher Cleaning

Even a little moisture leads to rust. Store in a dry place with a paper towel inside.
