While some Zwilling J.A. Henckels knives are labeled as dishwasher-safe, it is generally not recommended to put high-quality knives, including those from Zwilling J.A. Henckels, in the dishwasher. Dishwashing can have a negative impact on the performance, longevity, and appearance of the knives. Here's why:
Blade damage: Dishwasher detergents can be abrasive and may cause the knife blades to become dull, chipped, or scratched. The high water pressure and heat during the dishwasher cycle can also affect the blade's tempering, making it less sharp and more prone to damage.
Handle damage: The high heat and moisture in the dishwasher can damage the knife handles, especially if they are made of natural materials like wood. Wood handles may expand, contract, or even crack due to the dishwasher's conditions.
Corrosion and rust: Dishwashers can expose knives to prolonged moisture, which can lead to corrosion and rust on the blades, particularly if they are made from carbon steel.
Safety concerns: Placing knives in the dishwasher can create safety hazards when unloading the dishwasher, as the sharp blades might be hidden among other items, increasing the risk of accidents and cuts.
To preserve the quality and performance of your Zwilling J.A. Henckels knives, it's best to hand-wash them using the following steps:
Immediately after use, rinse the knives under warm water to remove food particles and residues.
Use a soft sponge or dishcloth and mild dish soap to gently clean the blades and handles.
Avoid abrasive pads or harsh cleaners that can damage the knife's surface.
Dry the knives thoroughly with a clean towel after washing to prevent moisture-related issues.
Store the knives in a knife block, magnetic strip, or on a magnetic knife rack to protect the blades and keep them accessible.
By following these hand-washing guidelines, you can extend the life of your Zwilling J.A. Henckels knives and ensure they remain in optimal condition for a long time.
