cleaning keyboards in the dishwasher

I have a workroom that has a large sink with hot and cold water flow, a parts washer made by Maytag, a big box made by Kenmore for chilling and storing cold stuff, including a section that stays below 0 degrees c, a box for heating stuff (thermostatic control up to about 500 degrees F) made by Tappan, (heating and chilling stuff can make assembly a lot easier) a flat surface heater made by Jenn-Air (including an open grill section for heater circuit boards, an exhaust fan, a timer controlled box full of microwaves, a bunch of cabinets and drawers for tools and supplies, such as mixers, graters, cutting tools, tongs, etc. Only problem is that when my girlfiend was living with me, she kept calling my workroom "the kitchen", and trying to use my tools for other purposes.
