We get it: The moment that dishwasher is open, you want to toss everything in and hit start. You’d be wise,however,to pause before stacking your favorite chef’s knife or cutting board inside.The extreme heat and powerful wash cycles can seriously damage your gear. We’re talking warping, rust, dulling, and cracking — issues even “dishwasher-safe” items aren’t always immune to.
Whether you’re breaking in a new dishwasher or you’re a veteran of automated cleaning, the urge to cram everything inside can lead to heartbreak later.
So before you run that next cycle,double-check what you’re tossing in. Your knives,skillets and
Cast iron skillets need to be seasoned, and the dishwasher will strip away that protective layer.
Cast iron cookware is prized for its even heating and durability, but it requires special care. The dishwasher’s harsh detergents will remove the seasoning – the layer of baked-on oil that protects the iron and makes it nonstick – leading to rust and damage. Always wash cast iron by hand with mild soap and warm water, and dry it thoroughly before lightly oiling it.

Why You Shouldn’t put Wooden Items in the Dishwasher
Wooden utensils and hot water are not a good mix.
Anything made from wood can be ruined if run through the dishwasher. This includes cooking utensils, spoons, chopsticks, bowls, and anything else. Wooden items should always be hand washed.

here’s how to properly care for your wooden kitchen tools:
- Wash by hand: use warm, soapy water and a soft sponge.
- Dry promptly: Don’t let wood sit in water.
- oil regularly: Apply food-grade mineral oil to keep the wood hydrated and prevent cracking.
- Avoid soaking: Never submerge wooden items for extended periods.
Taking these simple steps will extend the life of your wooden kitchenware and keep them looking their best. Proper care ensures they remain safe and hygienic for cooking.
