Why You Shouldn’t Use Dish Soap on Cast Iron
Share
If you’ve ever Googled “Can I use soap on cast iron?” you’ve probably seen conflicting advice. Some say it’s fine. Others swear it’s a crime. So what’s the real deal?
Here’s the short answer: dish soap and cast iron don’t mix — especially if you care about preserving your seasoning.
🧼 What Dish Soap Actually Does
Dish soap is designed to cut grease. But your cast iron seasoning is made of... grease — more specifically, baked-on layers of oil.
That means every time you use soap, you’re slowly breaking down the very thing that gives your pan its slick, non-stick surface.
