I'm a bit neurotic about keeping my microwave clean. Case in point: I clean it after EVERY use. I just use a Lysol wipe or at least a damp paper towel, whatever's handy (or whatever is needed for the clean-up job!). I don't want nasty bits of food getting nuked onto the walls, door, ceiling, turntable... and then splatting, falling or baking into whatever I am cooking or reheating! YUCK!
Here's an example -- or two -- of those not-so-clean nuke machines. You've seen them before. You may even own one! (And, no, these are NOT photos of my microwave!!! But you knew that.... right?!?!)
Does anyone feel a bit sick now?
At any rate, if your microwave (or that nasty one at work that NO ONE ever cleans) has gotten a bit funky of late, here is a neat little tip from my neat freak cheat sheet for an easier clean-up:
Get a microwave-safe bowl and fill it about half full with water and lemon juice. Microwave it on high until "boiling" (or at least until you get some good steam!) The citric acid will help to cut through grease and grime, and the steam will help loosen that stuck-on gunk! (Just please be careful NOT to touch the bowl or the hot water! Just let it cool down... those microwave "boils" can be a bit "iffy." And you don't want to get burned. Literally!)
Now, THAT's neat!
