removing pet stains: The steps are the important part. Pour enough vinegar to soak the stain and THEN add a small amount of baking soda. If you do the reverse, you will have a bubbly mess. Do it the right way, and you can hear it cackling.. it is cleaning and deodorizing without leaving residue. let the spot dry for a day or two before sweeping up and then vacuuming. We cover the spot with a bowl or plate so that we don’t have baking soda kicked. Works on old stains too!
