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

13. Antique or Hand-Painted Dishes

These items may lose their decorative finish or become damaged by repeated dishwasher use.

14. Plastic Containers Not Marked Dishwasher-Safe

Thin plastics may warp under high temperatures or release unwanted chemicals if not designed for dishwasher use.

15. Gold-Trimmed Tableware

Gold accents can fade or peel after repeated exposure to dishwasher detergent and heat.

16. Kitchen Items with Adhesive Labels

Heat and water may loosen labels, leaving sticky residue throughout the dishwasher.

17. Delicate Serving Pieces

Serving platters, decorative bowls, and specialty utensils are often better protected through gentle hand washing.

18. Lids with Rubber Seals

Some lids contain removable gaskets that can deteriorate or lose their shape in high heat unless specifically labeled dishwasher-safe.

Tips for Protecting Your Kitchenware

To keep your cookware and utensils in great condition:

• Read the manufacturer’s care instructions before washing.
• Use mild dish soap and warm water for delicate items.
• Dry wooden and cast iron items immediately after washing.
• Avoid soaking wooden tools for extended periods.
• Reserve the dishwasher for items clearly marked as dishwasher-safe.

The Bottom Line

A dishwasher can handle many everyday kitchen tasks, but it’s not suitable for everything. Taking a few extra minutes to hand wash delicate, valuable, or specialty kitchen items can help preserve their appearance, performance, and longevity. When in doubt, check the manufacturer’s recommendations to ensure you’re using the safest cleaning method.
