While dishwashers can save time and effort in the kitchen, not everything belongs in this appliance. By avoiding these ten items in your dishwasher, you can maintain the integrity of both your kitchenware and your appliance. Remember, when in doubt, it’s always best to hand wash delicate or valuable items to ensure they last for years to come! Here’s a rundown of ten items you should avoid putting in the dishwasher, along with the reasons why and tips for proper care.
Wooden Utensils and Cutting Boards
Why: Wood can warp, crack, or lose its finish in the high heat and moisture of a dishwasher. Over time, this can make them unsanitary and unsafe for food preparation.
Tip: Hand wash with mild soap and water, and dry immediately to preserve their longevity.
Non-Stick Cookware
Why: The harsh detergents and high temperatures can damage the non-stick coating, leading to peeling and reducing its effectiveness.
Tip: Clean with a soft sponge and mild detergent to maintain the non-stick surface.
Fine China and Crystal
Why: Many fine china pieces and crystal glasses are not dishwasher safe due to their delicate nature. High temperatures and water pressure can chip or crack them.
Tip: Always check the manufacturer’s instructions. Hand wash delicate items to ensure they remain intact.
Cast Iron Cookware
Why: Cast iron should never be put in the dishwasher, as it can strip away the seasoning and lead to rusting.
Tip: Clean with hot water and a stiff brush, then re-season if necessary.
Certain Plastics
Why: Not all plastics are dishwasher-safe. Some can warp or leach harmful chemicals when exposed to high heat.
Tip: Look for labels indicating dishwasher safety, or hand wash items that are not explicitly marked.
Knives
Why: The high heat and water pressure can dull knife blades and damage the handles. It can also pose a safety risk when loading and unloading.
Tip: Hand wash knives with a gentle sponge and dry them immediately to maintain their sharpness.
Insulated Mugs and Tumblers
Why: The heat can compromise the vacuum seal of insulated containers, leading to decreased effectiveness in keeping beverages hot or cold.
Tip: Hand wash these items with soap and water to preserve their insulation.
Paint or Stained Glass
Why: The dishwasher’s heat and moisture can damage painted surfaces or stained glass, leading to fading or peeling.
Tip: Clean these items carefully by hand with a soft cloth and mild soap.
Food Containers with Adhesive Labels
Why: Labels can break down and clog the dishwasher’s filter, leaving residue on your dishes. Adhesives can also warp plastic containers.
Tip: Remove labels before washing or use containers designed to withstand the dishwasher.
Electronics
Why: Items like blenders, coffee makers, or any electronic appliances should never go in the dishwasher. Water can damage the electrical components, rendering them useless.
Tip: Wipe down electronics with a damp cloth and use mild cleaners if necessary.
