How to Fix 17 Basic Cooking Mistakes
Putting Good Knives in the Dishwasher
Why it’s bad: Convenience comes at a price. The high-pressure water jets in a dishwasher cause knife blades to knock against other utensils
in the silverware basket, dulling and damaging them over time, says Symon. (Unfortunately, a dishwasher that has a specially
designed knife rack isn’t much better: The blades can still rattle against the sides of the rack.) Additionally, the intense
heat of the drying cycle can cause knife handles to warp, which will eventually loosen the rivets.
Do this instead: Wash knives by hand. Hold the handle so the blade faces away from you and wipe it clean with a sponge. Dry knives immediately to avoid the risk of discoloration from water droplets left on the blades. Just a few seconds of work will add years to the lives of your knives.
