Why Proper Cleaning Is Important

A cast iron skillet can be your kitchen BFF—with the right care. Proper cleaning not only keeps it looking good but also keeps it non-stick and even-heating. With just a little TLC, a good skillet, like a Lodge Cast Iron Skillet, will keep whipping up drool-worthy dishes for years to come!

Cleaning Must-Haves

Here’s what you’ll need:

How to Clean Your Cast Iron Skillet

Step 1: Cool Down the Skillet

Before cleaning, allow your skillet to cool to avoid cracking. (Besides, handling a hot skillet is risky business!)

Step 2: Remove Food Residue

Use a plastic or wooden spatula to scrape away any stuck-on food. This ensures you don’t need to over-scrub later, preserving the skillet’s seasoning.

Step 3: Scrub with Salt

Sprinkle a generous amount of coarse salt into the skillet, and then use a damp sponge or scrub brush to gently scrub away food particles, cleaning without damaging the surface.

Step 4: Rinse and Dry

Rinse the skillet under warm water to remove any remaining salt and residue. Immediately dry it with a paper towel or dish towel to prevent rust.

Step 5: Apply a Thin Layer of Oil

Add a small amount of cooking oil to the skillet. Use a paper towel or silicone brush to spread a thin, even layer over the surface, inside and out. This helps maintain the seasoning and protects against rust.

Tips for Maintaining Your Cast Iron Skillet

  • ● Cook with fat-rich foods: This naturally adds to the seasoning.
  • ● Avoid soaking: Prolonged exposure to water can cause rust.
  • ● Store it properly: Keep your skillet in a dry place, ideally with a paper towel between pans to absorb moisture.
  • ● Re-season as needed: If food starts to stick, it’s time!

Avoid using harsh soaps or steel wool, letting the skillet air-dry and cooking acidic foods (like tomatoes) for extended periods, especially in a new skillet.
