Replace Your Sponges Regularly, Affordably

How often sponges should be replaced vary largely from every two weeks, once a month, to a every few months. I prefer to replace mine every month, considering the contaminant exposure my sponges face: raw poultry and meat juices leftover on cutting boards, fats and greases from various foods, the damp and moist environment sponges live in, etc. Experts claim that sponges can be as dirty as raw poultry! To make replacements more affordable, I buy my sponges at the 99 cents store. I get 6 sponges for 99 cents! They're surprisingly durable and don't scratch my cookware surfaces.
