All the cloths I have seen in peoples kitchens looked like they should have been thrown
out a long long long time!
I have a fear of them....So I use the sponge, and it is washed out with anti bacterial all the time, and boiling hot water.
The boiling hot water is the trick, cloths seem to collect in the fibers, and are too big also.
Apparently they are a breading ground for harmful e coli and the rest!
I have heard people say they put theirs in the washer, and that makes me wince.
Vee: I am such a 'germaphobe' I have 18 tea towels, all cotton and once one has been used for the day , it is washed (alone)....I'm also a tad of a clean freak. :/
