Microwaves get dirty so easily, and yet, you can conveniently close the door on said dirt and not think about it while cleaning up the kitchen. Or at least, I am guilty of that, until suddenly I look in there and am struck by the shame of living in such filth.

Cleaning the microwave can be a pain, since all the food is crusted on.  To clean it up fast, fill a coffe cup halfway with water and add a generous splash of lemon juice. Microwave the cup until the water begins to boil.  The steam and lemon juice will allow you to wipe everything off no trouble at all.  You may need to return the cup to the microwave and reheat it if it starts getting difficult again.  Be careful not to burn yourself with the cup! Been there, done that.

Oh, and I usually use bottled lemon juice for this, and the bottle I have in the fridge for this purpose is long expired and it still works fine.  Just make sure no one uses it for food! If you don’t have lemon juice, heating water by itself will work, too, but not quite as well.
