Everyone has been there, you come home and your pet has left a present for you. The import thing with treating pet urine on carpet is to get all of it out of the carpet and the padding. You can use a black light to find the entire area of the stain. Use a mixture of club soda and warm water (about half and half) to pour over the area, using lots of paper towels to blot the area well, until it is dry to the touch. Then
sprinkle on a liberal amount of baking soda and let that stand for at least a day. Vacuum up the baking soda. Be sure to clean the filter on your vacuum afterward as the baking soda tends to lessin the suction power of most vacuums.
