It is generally not recommended to put expensive kitchen knives into a dishwasher. Here's why:
Blade damage: Dishwashers use high-pressure water jets and strong detergents, which can be harsh on knife blades. The intense agitation and banging against other utensils in the dishwasher can cause the blades to chip, dull, or become damaged.
Handle damage: The heat and moisture in the dishwasher can affect the handles of knives, especially if they are made of wood, plastic, or other materials that are sensitive to these conditions. This can lead to warping, cracking, or loosening of the handle.
Risk of accidents: Placing sharp knives in the dishwasher increases the risk of accidents when unloading the dishwasher. If someone reaches into the dishwasher without being aware of the knives, they can potentially cut themselves.
To maintain the quality and longevity of your expensive kitchen knives, it is generally best to wash them by hand. Here are some guidelines to follow when handwashing knives:
Clean immediately after use: Rinse the knives right after use to remove any food particles and prevent them from drying and sticking to the blade.
Use warm soapy water: Fill the sink with warm water and mild dish soap. Gently hand wash the knives one at a time, avoiding harsh scrubbing or abrasive materials that could damage the blade.
Handle with care: Be mindful of the sharp blades while washing and drying the knives. Hold them by the handle and avoid touching the blade directly.
Dry thoroughly: After washing, dry the knives immediately with a soft towel. Moisture can cause the knives to rust, so make sure they are completely dry before storing them.
Proper storage: Store your knives in a knife block, on a magnetic strip, or in a knife guard/sheath to protect the blades and prevent accidents when retrieving them.
By following these handwashing practices, you can keep your expensive kitchen knives in excellent condition and ensure their longevity.
