They may move around during the wash cycle and come into contact with heating components.
If they are not clearly designed for dishwasher use, wash them by hand.
## 16. Items With Adhesive Labels
Containers with paper labels or stickers can create a mess inside the dishwasher.
Labels may:
Dishwashers
* peel off
* clog filters
* stick to dishes
* leave adhesive residue
* interfere with drainage
Remove labels before washing reusable jars or containers.
## 17. Anything With Electronic Components
This may sound obvious, but certain modern kitchen tools contain hidden electronics.
Examples include:
* digital thermometers
* battery-operated gadgets
* electronic measuring devices
* some illuminated cups or bottles
* smart kitchen accessories
Unless the manufacturer explicitly says the removable part is dishwasher-safe, keep electronic components away from the dishwasher.
## 18. Hand-Painted, Personalized, or Sentimental Items
Customized mugs, handmade pottery, printed glasses, and decorative kitchenware may not withstand high heat or harsh detergent.
Dishwasher cycles can cause:
Dishwashers
* fading
* cracking
* peeling
* discoloration
* damage to printed designs
If an item is valuable because of its appearance or sentimental importance, hand washing is usually worth the extra minute.
## What About “Dishwasher-Safe” Labels?
A dishwasher-safe label generally means the manufacturer considers the product capable of withstanding dishwasher use under recommended conditions.
But that does not necessarily mean the item will remain unchanged forever.
Repeated cycles can still gradually affect:
* coatings
* printed designs
* sharp edges
* decorative finishes
* silicone seals

For expensive or delicate items, hand washing may still extend their lifespan.
