Microwave Tips

microwave



  • Keep the interior clean. Vapor can transfer grease and residues to the cavity, causing rust and corrosion of the interior.
  • Never cook popcorn directly on the bottom!! These little bags have foil strips on the inside which will instantly discolor the bottom and warp the turntable. Instead, place popcorn on an inverted plate or bowl.
  • Always cover every item, especially the potatoes. Food gives off steam which starts the corrosion process.
  • If you have a turntable, be sure to clean under it regularly.
  • The metal racks which come with some models are a convenience only, and should not be left in the unit if cooking on the turntable.
