While dishwashers are designed to handle a wide range of dishes and utensils, there are certain items that should not be placed in a dishwasher. Here are some things you should avoid putting in a dishwasher:
Wooden items: Wooden utensils, cutting boards, or wooden-handled items should not be washed in a dishwasher as the hot water and prolonged exposure to moisture can cause them to warp, crack, or lose their finish.
Cast iron cookware: Dishwashers can strip away the seasoning of cast iron cookware and promote rusting. It's best to wash cast iron pans by hand using minimal soap and dry them thoroughly.
Delicate glassware: Fine glassware, crystal, or antique glass items are susceptible to chipping, cracking, or clouding in the dishwasher due to the high water pressure and heat. It's safer to wash them by hand.
Non-stick cookware: Dishwashers can gradually degrade the non-stick coating on pans and pots. It's generally recommended to wash non-stick cookware by hand to prolong their lifespan.
Insulated mugs or bottles: Items with insulated vacuum walls, such as travel mugs or thermoses, should not be placed in the dishwasher as the high heat and pressure can damage their insulation properties. It's best to hand wash them.
Certain plastics: While many dishwasher-safe plastics exist, some plastics are not suitable for the dishwasher as they can warp or release harmful chemicals under high heat. Always check the product label or manufacturer's instructions to determine if the plastic item is dishwasher-safe.
Aluminum items: Uncoated aluminum utensils or cookware can react with the detergent or other components in the dishwasher, leading to discoloration or damage. It's advisable to wash aluminum items by hand.
Sharp knives: Dishwashers can dull the blades of sharp knives and cause them to come into contact with other items, potentially leading to accidents or damage. It's best to hand wash knives with care.
Items with adhesives: Items with adhesive labels, stickers, or glue may not withstand the heat and water pressure in the dishwasher, causing them to come loose or leave residues on other items.
Always refer to the manufacturer's instructions or product labels for specific guidelines on dishwasher suitability. When in doubt, it's generally safer to hand wash delicate or questionable items to avoid any potential damage.
