Ok, showing how dumb we can all be some times. I tried this after my son was born. We started sterilizing his bottles using a steamer in the microwave. Well, I figured it would be just as effective for sponges! Let's face it, those kitchen sponges get really smelly and nasty after a while - no matter what they say about "germicidal". Unfortunately, I also tried it w/ a not-completely-wet sponge. Damp won't do it, the thing has to be SOAKING wet. I put a damp one in there for 2 minutes - enough time to boil water - and burned a hole right through the middle of it.
Now, thanks to HIGH-TECH RESEARCH (I'm embarrassed to say it's my alma mater) I know that if I soak the thing, it actually DOES kill the germs!
