## Items That Can Also Damage Your Dishwasher
Certain objects are not only at risk themselves—they can create problems for the machine.
Avoid putting loose items inside that could:
* fall through the racks
* block spray arms
* clog the filter
* melt onto heating components
* break into sharp fragments
Small lids and lightweight utensils should be secured properly before running a cycle.
## A Simple Rule to Remember
Before putting an unfamiliar item in the dishwasher, ask three questions:
1. Can high heat damage it?
2. Can strong detergent damage its finish?
3. Can prolonged water exposure cause rust, warping, or loosening?
If the answer to any of these is yes, washing by hand is probably safer.
## The Bottom Line
Dishwashers are excellent for everyday plates, glasses, stainless-steel cutlery, and cookware specifically labeled dishwasher-safe.
But wooden utensils, cast iron, fine knives, delicate china, crystal, copper, certain plastics, insulated containers, and sentimental items often last longer when washed by hand.
Taking an extra minute to check the material can prevent ruined cookware, damaged finishes, and unnecessary replacement costs.
