FAQ: Is it ok to clean my kitchen knives in a dishwasher?
28th Jul 2015
NO.
Your dishwasher uses very high heat and nasty chemicals to get the food off of your dishes -- and none of that is good for your fine knife. What's more, imagine all of those chunks of food aggressively pressure-washing your blade.
No wonder knifemakers cringe whenever someone even mentions dishwashers.
Dishwashers ruin knives -- period. Just don't do it.
