Easy off now has a special cleaner just for microwave ovens.

The product works in three easy steps:

• Place the pouch in the microwave and set on "high" for one minute.
• Pouch pops open and releases cleaners that coat the interior of the microwave oven.
• Wait for three minutes to cool, then wipe interior clean with the towelette.

Okay, so it doesn't really explode, but for some reason I get this image of it exploding in a mess of cleaning fluid when I think 'pops open'. Kind of like microwaving an egg. I'm sure it is nowhere near that cool.
