I used the Paws & Claws Carpet Cleaning Formula with Stainguard with the Odor Neutralizer Enhancer. The combination of both of these products together work amazing and smell amazing. It's very easy to use and really leaves my carpet and house smelling and looking clean. You just pour 3 ounces in your filled water tank and that's it. It definitely removes pet odors and stains (and children's stains) much better than other formulas I have tried. It's supposed to help protect against future stains, so I hope this is the case. It works great and smells great - I will definitely continue to use this cleaner.
