How To Scrap A Microwave Safely

The capacitor should be shorted out to ensure there is no electrical charge left in it, but even those will slowly lose their charge over time, so unless it has been plugged in within a day or so of your poking your fingers in it the charge is pretty much gone anyway.And be sure not to try discharging the capacitor with other pieces of your body!!

You mean the way Hoss did the TV?? If I remember correctly there is a bleed-off resistor attached to one lead of the microwave cap, and that should drain the "juice" off.
