1. Preparation
   • Dishwasher
     • Make sure the dishwasher is clean and empty. (Did I really need to say that?)
     • Disable heat-dry, auto-temp, and any other heat-producing features.
     • If possible, set to warm rather than hot water.
     • Load a very small amount of liquid dishwashing (not dishwasher) detergent.
   • Oven
     • Make sure the oven is clean and empty.
     • Preheat to 65°C (150°F).
     • If it's electric, you might want to place baking sheets on the racks above and below where the keyboard will go. (i.e. having a glowing red element near a keyboard is not a good thing.)
   • Keyboard
     • Remove obvious dirt with cloth and vacuum cleaner.
     • Disconnect (or coil and twist-tie) the cord.
2. Cooking
   • Place the keyboard, upside down, on the top rack of the diswasher.
   • Run on gentle cycle.
   • When you hear the dishwasher filling with water, if it didn't have a warm-water setting, add a litre or so of cold water, and let it continue.
   • When it enters the dry cycle:
     • Stop it and remove the keyboard.
     • Rinse under a tap, and shake well, holding the keyboard in various orientations.
   • Repeat all this again, but on rinse-cycle only, and without detergent.
   • Shake as much water as possible out of the keyboard. If you can still hear sloshing, it's not ready yet.
3. Baking
   • Make sure that the oven has been preheated.
   • Bake for about 2 hours.
4. Presentation
   • Remove from oven, cool, and serve.
   • Do not top with ice-cream.
