Love sponges in the kitchen but not the spread of household germs? Keep your sponges neat and clean simply! Each morning, rinse your sponge with a little soap. Leaving it wet, microwave it for three minutes. Be careful as it will be steamy!
I just tried this tip and the sponge almost caught on fire. I don't think I would leave it in for three minutes. (05/23/2007)
By I don't think I would try it
Sponge size and microwave power would effect the amount of time to sterilize a sponge. What is and ordinary size of a kitchen sponge? I have not found any reference other than ordinary kitchen sponge as to size or the microwave wattage when on high.
