No, you should not put ceramic knives in the dishwasher. While technically they are dishwasher safe, it’s very likely that your ceramic knives will get damaged in the dishwasher. Ceramic blades are much more fragile than stainless steel, and will break in the jostling dishwasher. Honestly, no chef knives should be going in the dishwasher, as everything gets rubbed up against each other in there and this will dull, if not damage, the blade. If you did put your ceramic knife in the dishwasher, don’t fret, but don’t do it again.
Instead, simply wash your ceramic knives by hand with a mild dish soap and a sponge. Dry thoroughly immediately after washing. Following these simple care tips will have your ceramic knives lasting for a long time.
