7. Copper Cookware
Why: Loses shine, develops tarnish, and may leach metal if unlined.
Do this: Wash by hand; polish occasionally with lemon + salt or commercial copper cleaner.
8. Fine China & Gold- or Platinum-Rimmed Dishware
Why: Metallic accents fade or peel; delicate glazes can crack.
Do this: Hand-wash in warm, soapy water; dry with lint-free cloth.
9. Crystal Glassware & Hand-Blown Glass
Why: Extreme heat can cause cloudiness or thermal shock (cracking).
Do this: Wash gently by hand; avoid sudden temperature changes.
10. Graters, Garlic Presses & Small Gadgets with Crevices
Why: Food gets trapped in tiny spaces—dishwasher won’t fully clean them.
Do this: Use a small brush (like a toothbrush) under running water right after use.
Bonus: “It Depends” Items (Use Caution)
Stainless steel: Usually safe—but check manufacturer guidelines.
Silicone bakeware: Generally dishwasher-safe (top rack recommended).
Plastic containers: Only if labeled “dishwasher-safe” (and place on top rack to avoid warping).
The Bottom Line
Putting the wrong item in the dishwasher might save 30 seconds today—but cost you ruined cookware, dull knives, or cloudy glassware tomorrow.
“Taking care of your tools isn’t extra work—it’s how you make them last a lifetime.”
When in doubt? Hand-wash it. Your kitchen will thank you for years to come.
