The image above shows a dishwasher that has suffered a catastrophic failure, with shattered glass scattered across the racks and the kitchen floor. The caption describes a terrifying incident where the appliance “exploded,” sending glass everywhere, and notes that a professional advised being more careful about what goes inside.
While a dishwasher is a convenient appliance, it is not designed to handle every item. Certain materials can break, warp, or cause damage to the machine itself. Here is a list of eight items that should never be placed in a dishwasher.
1. Certain Types of Glassware
Not all glass is dishwasher-safe. Delicate glassware, crystal, and antique glass can weaken over time when exposed to high heat and harsh detergents. This can lead to cracking or, as the image shows, shattering. Always check for a “dishwasher safe” label before placing glass items in the machine.
2. Cast Iron
Cast iron cookware is seasoned with a layer of oil that protects it from rust and gives it a non-stick surface. Dishwasher detergent is too harsh and will strip away this seasoning, leaving the pan vulnerable to rust. Hand washing and immediate drying are the best ways to care for cast iron.
3. Wooden Items
Wooden spoons, cutting boards, and bowls can warp, crack, or split when exposed to the prolonged heat and moisture of a dishwasher. The harsh detergent can also strip the natural oils from the wood, causing it to become dry and brittle.
4. Knives with Sharp Edges
The high heat and water pressure in a dishwasher can dull the blades of sharp knives. Additionally, the handles can loosen or crack over time. It is always best to wash knives by hand to preserve their sharpness and longevity.
5. Non-Stick Cookware
The coating on non-stick pans can degrade when exposed to the high heat and abrasive detergents used in dishwashers. This can cause the coating to peel or flake, ruining the pan and potentially releasing harmful particles into your food.
6. Aluminum Cookware
Aluminum pots and pans can react with the alkaline detergents used in dishwashers, causing them to discolor, pit, or develop a chalky white film. Hand washing is the safest way to maintain their appearance and function.
7. Insulated Mugs and Travel Cups
Insulated mugs and travel cups often have a vacuum seal between the inner and outer walls. The high heat of a dishwasher can compromise this seal, causing the insulation to fail and the cup to lose its ability to keep drinks hot or cold.
8. Fine China and Antiques
Fine china, antique porcelain, and items with delicate hand-painted designs or gold trim should always be washed by hand. The harsh detergent and high heat can fade the colors, damage the glaze, and cause the items to crack.
Conclusion
The incident shown in the image is a stark reminder of the importance of knowing what is safe to put in your dishwasher. Taking a moment to check whether an item is dishwasher-safe can prevent damage to your belongings and, more importantly, keep your family safe from injury.
