Well trying to get the house in selling condition takes up a lot of time, so probably no food posts up in the near future. So I decided to go with a tip that helps me a lot.
I don't know if everyone else's microwave gets as nasty as mine does, but it helps to have a method that makes cleaning it a breeze.
What I do is take your standard kitchen cleaner and throughly spray the interior of the microwave including the inside of the door until it is dripping. Then place a microwave safe bowl half filled with water inside. Set it for about 4 minutes on high and let it go. After the timer goes off let it sit for 5 minutes or so, then open and carefully remove the water bowl, it will be very hot.
Then just wipe the muck up with a rag, it comes off real easy, for me anyway.
Hope this helps, and until next time...
