It is generally not recommended to put long knives in a dishwasher. Dishwashers can cause damage to the blades of knives and may lead to potential safety hazards. Here's why:
Blade Damage: The high-pressure water jets and the movement of dishes during the dishwasher's cleaning cycle can cause the long knives to bump against other dishes or the dishwasher's interior, leading to chipping or dulling of the blade.
Safety Hazard: Placing long knives with exposed blades in the dishwasher increases the risk of injury when unloading the dishwasher. You or someone else may accidentally come into contact with the sharp blade while reaching for other dishes.
To safely clean long knives, it's best to follow these alternative methods:
Handwashing: The safest way to clean long knives is by handwashing them. Use warm, soapy water and a sponge or dishcloth to clean the blade carefully. Make sure to wash both sides of the blade and the handle. Rinse thoroughly, and then dry the knife with a clean towel.
Knife Block or Magnetic Strip: Store your long knives in a knife block or on a magnetic strip on the wall. This way, they are easily accessible, and you can keep the blades protected and away from other dishes or utensils.
Knife Guards or Blade Covers: Some knives come with blade guards or covers. These protect the blade while in storage and can also be used during transportation or travel.
If you absolutely must put knives in the dishwasher due to limited space or other reasons, use a dishwasher utensil basket or a dedicated knife rack that holds the knives securely and keeps the blades separated from other items to minimize the risk of damage or injury. However, handwashing remains the best and safest option for cleaning and maintaining the longevity of your long knives.
