My neighbors have been into these new cleaning products from Norwex. They kept talking about how great they are and how they are good for the environment so I thought I would try them. Last month I bought the cloth and the window cloth. I liked them. I could use them more then just once without them getting stinky so this month I bought the Spirinet. Its this sponge thing that is suppose to help with hard water stains. They also have a spray for hard water stains but I figure I will buy that next month. I tried it out and it is a miracle! I am almost embarrassed to show the before picture because it looks like I never clean but, I just have not found anything that gets the crap off.
