Kitchen knifes are also infamously not dishwasher safe. Mine’s got wooden handles but they were slightly worn from not drying them immediately when handwashing. Ever since I got a dishwasher I chugged them in there and they have survived without any more damage.

Generally the reason not to put knives in the dishwasher is because the mild abrasives used in some detergents, and more importantly the agitation which bonks them around, can both dull the edge (and damage the coating on the racks that prevents your dishwasher from rusting, if you have one that isn’t full plastic).

  Which means some can be pretty well cleaned in a top utensil rack which are made of plastic and the knife can be placed to rest on the dull side. Abrasives you should avoid, though the rack has light touch anyway. And handle should be plastic.

    Are there nonabrasive dishwasher detergents?
