No animal ever gets into my bathtub. Yuck. I just bought these a few weeks ago and thought it was just the new rubber smell that would wear off. It hasn't and I've thrown them in my front load washer and still no luck. After every use, I pull them up and hang them over the tub to dry out, too. Please, someone help me get rid of the problem. No silly posts, please. I've just joined this site for honest answers.
