**8 things you should never put in the dishwasher** (and why)

7. Copperware

Copper pots and pans are prized for their excellent heat conduction and attractive appearance, but they require special care. Dishwasher detergents and high temperatures quickly tarnish copper, causing dark spots and stains that diminish its natural shine. Certain detergents can chemically react with copper, leading to corrosion that damages the metal’s surface.

To keep copperware looking its best, always wash by hand using mild soap and warm water. Rinse and dry immediately to prevent water spots. Regular polishing with commercial copper cleaners or homemade pastes made from lemon juice and salt will maintain the bright finish and remove tarnish.

8. Antique or valuable porcelain

Antique or hand-painted porcelain often carries significant sentimental and monetary value, so preserving its condition is essential. Dishwashers are too harsh for these delicate items; the high heat, strong detergents, and mechanical agitation can cause fading, cracking, or chipping of the glaze and painted designs. Over time, repeated dishwasher cycles will degrade these valuable pieces irreversibly.

Hand washing with gentle detergent and lukewarm water is the only safe method. Use a soft sponge or cloth and avoid abrasive scrubbers. Rinse thoroughly and dry with a lint-free cloth. Store carefully to avoid damage.

When to See a Doctor

While this article focuses on kitchenware care, it’s important to note that injuries such as cuts from sharp knives or chemical exposures from cleaning agents require medical attention if severe. If you experience deep cuts, persistent pain, signs of infection, or adverse reactions from cleaning products, seek prompt evaluation by a healthcare professional.

Conclusion

Protecting your kitchen tools and valuable items from dishwasher damage preserves their function, appearance, and lifespan. Sharp knives, wooden utensils, delicate glassware, cast iron, non-stick pans, items with adhesive labels, insulated mugs, copperware, and antique porcelain all require hand washing or special care. Following the recommended cleaning methods will save you money on replacements and keep your kitchen running smoothly for years to come.
