Putting Them in the Dishwasher

Hertzmann maintains that taking care of any knife will make the biggest impact on how it will perform. And when it comes to cleaning, he says that regardless of what the knife costs, you shouldn't put it in the dishwasher, however tempting it may be. Most soaps are too corrosive, and the high temperatures can warp the handle. Instead, carefully hand wash them in hot, soapy water.
