It may seem like the easiest way to clean them, but the dishwasher can shorten the life of a good knife.
Even when a knife is labeled dishwasher-safe, hand washing is still the best way to protect its blade, edge, handle, and finish.
The edge can lose its sharpness
Inside the dishwasher, knives may hit cutlery, plates, or other utensils.
These small impacts can gradually damage the cutting edge and cause the knife to lose sharpness and precision.
Very hard or thin blades may even develop small chips.
Dishwasher detergents are harsh
Dishwasher detergents are stronger and more abrasive than regular dish soap.
Over time, they may: Dull the blade’s finish Cause surface stains Affect rivets and joints Damage certain handle materials
Heat and moisture can cause damage
High temperatures and steam can affect handles made from wood, resin, composite materials, or bonded components.
If the knife remains damp after the cycle, small rust spots may appear, especially near the edge or around the joints.
Stainless steel is highly resistant to corrosion, but it is not completely immune to moisture, salt, or strong detergents.
It is also a safety issue
Knives can be dangerous when loading or unloading the dishwasher, especially when the blade is hidden among other utensils.
Hand washing allows you to see and control the knife more safely.
The best way to clean your knife
After each use: Wash it with warm water, mild dish soap, and a soft sponge. Hold it securely by the handle. Clean the blade away from your body. Rinse it carefully. Dry it immediately. Store it in a knife block, on a magnetic strip, or inside a blade guard. Never leave a knife submerged in the sink. It is unsafe and prolonged contact with water may damage both the blade and the handle.
