How to Properly Clean Your Gross Kitchen Sponge

How to Properly Clean Your Gross Kitchen Sponge
From Lifehacker - August 7, 2017

You wipe your kitchen sponge all over the grossest things in your sink, so it makes sense that it would accumulate some pretty gross bacteria. But is it possible to clean or sanitize that sponge? Yes, it turns outbut only as a short-term fix.

The Headline: Cleaning a Dirty Sponge Only Helps Its Worst Bacteria, Study Says (New York Times)

The Story: A team of German scientists analyzed the bacteria on 14 kitchen sponges, some that were cleaned regularly and some that werent. The results are interesting to microbiologists but not groundbreaking for the everyday sponge owner. To summarize:

When you kill all or most of the bacteria in a germy place, the bacteria move right back in, but sometimes the balance of species is a little different than it was originally: more of one type of bacteria, less another type. Thats what they found here (although we have to remember they only studied 14 of the millions of kitchen sponges in the world).

But theres no need to fear these bacteria: even the worst ones the New York Times article mentioned are pretty harmless. None cause diseases in healthy people. Even the one they name checked, Moraxella osloensis,can live happily on your skin without causing problems.
