18 Things You Should Never Put in the Dishwasher (Even If You’re Tempted)

1. Cast Iron Skillets

Dishwashers strip away the seasoned coating that gives cast iron its nonstick properties. They can also cause rust to develop.

2. Sharp Kitchen Knives

High-quality knives can become dull, and the blades may nick other dishes or become damaged during the wash cycle.

3. Wooden Cutting Boards

Heat and moisture can cause wood to warp, crack, or split over time.

4. Wooden Utensils

Wooden spoons, spatulas, and rolling pins absorb water, which can weaken the material and lead to cracking.
