8 Things You Absolutely Should Not Put in a Dishwasher (And Why)
When it comes to saving time in the kitchen, dishwashers are invaluable. They can handle a mountain of dirty dishes while we focus on other tasks. However, not all items are suitable for the dishwasher. Understanding what not to put in a dishwasher can prevent damage to your kitchenware and ensure your appliance runs efficiently. Here are eight things you absolutely should avoid placing in your dishwasher, along with explanations for each.
1. Wooden Utensils and Cutting Boards
Why Avoid?
Wooden utensils and cutting boards can warp or crack when exposed to the high temperatures and steam of a dishwasher. The constant moisture can also lead to bacterial growth if the wood is not properly dried.
Care Tips:
Instead, hand-wash wooden items with mild soap and warm water. Regular oiling with food-grade mineral oil can also help maintain their integrity and extend their lifespan.
2. Non-Stick Cookware
Why Avoid?
Many non-stick pots and pans have a special coating that can be damaged in the dishwasher. The heat and harsh detergents can strip away that non-stick surface, leading to food sticking and diminished performance.
Care Tips:
Clean non-stick cookware with a soft sponge and mild soap. Avoid abrasive pads or cleaners that can scratch the surface.
3. Fine China and Crystal Glassware
Why Avoid?
Fine china and delicate crystal can be too fragile for the dishwasher. The high heat and jostling during the wash cycle can cause chipping or breakage. Additionally, some glazes may contain materials that could leach in a dishwasher’s high heat environment.
Care Tips:
Hand-wash these items with care, using a soft cloth and gentle detergent. Dry them immediately to avoid water spots and maintain shine.
4. Plastic Containers
Why Avoid?
Many plastic containers can warp or melt in the dishwasher, especially if they are not labeled as dishwasher-safe. Even when labeled, the heat can cause plastics to release harmful chemicals into food.
Care Tips:
Choose microwave-safe and dishwasher-safe plastic and always place them on the top rack to minimize exposure to heat. Hand-washing is often the safest option.
5. Knives and Sharper Cutlery
Why Avoid?
Put knifes and sharper cutlery in the dishwasher, and they may dull over time due to the rough tumbling action. Additionally, dishwashing can lead to the risk of injury when loading and unloading sharp items.
Care Tips:
Wash your knives by hand using a soft cloth and mild detergent, then dry them immediately. This preserves the sharpness of the blade and keeps them safe.
6. Cast Iron Cookware
Why Avoid?
Cast iron cookware requires a specific cleaning method to maintain its seasoning. If washed in a dishwasher, the protective layer can be stripped away, leading to rust formation and a diminished cooking surface.
Care Tips:
Hand-wash cast iron with hot water and a stiff brush. Avoid soap entirely; instead, use kosher salt to scrub off any stubborn bits, then dry it immediately and apply a thin layer of oil.
7. Insulated Mugs and Containers
Why Avoid?
Insulated drinkware, like travel mugs and thermoses, can lose their thermal properties when subjected to the heat of a dishwasher. The seams and materials used to insulate can be compromised, affecting their performance.
Care Tips:
Always hand-wash insulated containers using a soft cloth and mild dish soap. This helps retain their ability to keep drinks hot or cold.
8. Certain Kitchen Gadgets
Why Avoid?
Many kitchen gadgets such as whisks, mortar and pestles, and graters may have components that can get damaged in the dishwasher. For instance, graters may have fine edges that can dull or bend, while whisks can get tangled with other utensils.
Care Tips:
Check the manufacturer’s guidelines for your gadgets and hand-wash them according to recommendations, ensuring longevity and effectiveness.
Conclusion
Knowing what not to put in your dishwasher is essential in prolonging the life of both your kitchenware and your appliance. From wooden utensils to fine china, understanding the best cleaning methods for each item ensures they remain functional and beautiful. For optimal results, always refer to the manufacturer’s instructions for your dishware and cookware, as they will provide the best guidance on maintaining your items. By following these precautions, you can enjoy the convenience of dishwashing without sacrificing the quality of your favorite kitchen tools and accessories.
