The dishwasher is one of the most convenient appliances in the kitchen, but not everything belongs inside it. High heat, strong detergents, water pressure, and long wash cycles can damage certain materials surprisingly quickly.

Some items may lose their finish, warp, crack, rust, or become unsafe to use. Others can even damage the dishwasher itself.
Here are 18 things that are usually better washed by hand.
## 1. Wooden Cutting Boards
Wood and prolonged hot water do not mix well.
Dishwasher cycles can cause wooden cutting boards to:
* warp
* crack
* split
* dry out
* lose their smooth finish
The heat can also weaken glued joints in laminated boards.
Wash wooden boards by hand with warm soapy water, rinse them promptly, and dry them upright.
## 2. Wooden Spoons and Utensils
The same rule applies to wooden spoons, spatulas, and handles.
Repeated dishwasher cycles may cause them to:
* become rough
* split
* fade
* absorb water
* loosen at glued areas
Hand washing usually helps them last much longer.
## 3. Cast-Iron Cookware
A cast-iron skillet should not normally go in the dishwasher.
The detergent and prolonged moisture can strip away the protective seasoning and encourage rust.
Instead:
* wash gently by hand
* dry immediately
* apply a very thin layer of cooking oil if needed
Proper care helps maintain the naturally seasoned cooking surface.
## 4. Carbon-Steel Pans and Knives
Carbon steel behaves similarly to cast iron.
Dishwasher detergent and moisture can damage the seasoning and promote rust.

Hand washing and immediate drying are usually the safer choice.
