How to Clean a Cast Iron Skillet After Every Use

This is the routine that protects your seasoning and keeps your skillet performing like a dream.

Do this after every single use and your cast iron will practically take care of itself.

• Leaving it wet — always dry on the stovetop after every single wash, no exceptions.

Habits That Make Cast Iron Last Generations:
