How do I properly clean my microwave oven?

Always unplug the appliance before cleaning, then wipe the cavity with a slightly damp cloth and clean accessories in soapy water. The door frame, seal, and neighboring parts should be cleaned carefully with a damp cloth. Do not use harsh abrasive cleaners or sharp metal scrapers on the oven door glass, as these can scratch the surface and may cause the glass to shatter. (Page 8)
