Cast iron skillets are beloved by home cooks for their incredible durability, natural non-stick surface, and superior heat retention. When properly maintained, a quality cast iron pan can last for generations.

However, one challenge many owners face is dealing with stubborn burnt grease and baked-on residue. Over time, layers of cooking oils and food particles can accumulate, leaving the skillet rough, sticky, and difficult to clean.

Fortunately, there’s a simple old-fashioned cleaning method that requires minimal effort and uses an ingredient most people already have in their kitchen.

This easy cast iron cleaning trick relies on a common pantry staple to loosen stubborn grease while helping preserve your skillet’s valuable seasoning.

Why Burnt Grease Is a Problem for Cast Iron

Even well-maintained cast iron cookware can develop grease buildup over time.

Common causes include:

• Cooking with high-fat foods
• Infrequent cleaning
• Excess oil during seasoning
• Repeated exposure to high heat

When grease accumulates, it can:

• Create sticky surfaces
• Affect cooking performance
• Cause uneven heating
• Produce unwanted odors
• Make food more likely to stick

Many people instinctively reach for harsh cleaners or steel wool, but these methods can damage the skillet’s protective seasoning layer.

The Simple Pantry Staple Behind This Cleaning Method

The secret ingredient is surprisingly simple:

Table Salt

Ordinary table salt works as a gentle abrasive that helps lift stubborn grease without aggressively stripping the pan’s seasoning.

Benefits of using salt include:

• Affordable
• Non-toxic
• Readily available
• Gentle on cast iron
• Easy to use

Combined with heat, salt can help break down cooked-on residue while preserving the skillet’s cooking surface.
