Sponges really do have a bad rep for being germ magnets! I, like others, use dishrags that get changed every day. I wash them in the washing machine with bleach as well. The thing about dish rags is that they do dry faster and easier but if they are not changed daily, they have the same issues that sponges have.
FYI,if you change a sponge and "lower" its position, you are just changing where you are putting all those germs, ie the bathroom. I do like those sponges that have the scratchy green side for cleaning the stove and floors but I only use them once, wring them out really good, and then wash them in the washer with the other rags and dry them in the dryer.
