Microwave Sponges to Kill Germs
Compliments of Moms Against "Cooties"
Moms Against Cooties would like to be able to use and reuse sponges without fearing that we were spreading germs. So, we set out to find the best way to clean sponges that have been in contact with foods such as raw egg, uncooked meat or raw vegetables. Turns out that the microwave oven may offer the simplest effective option, according to University of Florida researchers.
The scientists reported that simply microwaving sponges (completely wet, never dry) for two minutes at high power killed or inactivated over 99 percent of pathogens in sponges that had been soaked in a “witch’s brew” of fecal bacteria, viruses, protozoan parasites and bacterial spores.
Zap Sponges… But Watch Out
The researchers recommend “zapping” kitchen sponges every other day or so. Watch out though – the zapped sponges will be really hot and steamy, so should be left in the microwave for a few minutes to cool. And obviously, this method won’t work if the sponges contain any metal. Another option is to put the sponge into a dishwasher for a full wash and dry cycle.
