You’ve tackled the pee stain on the carpet, but that smell still lingers in the air. Yuck! Fortunately, you can use certain sprays to help remove the odor. A homemade baking soda spray, made with 1/4 cup of baking soda and 2 cups of water in a spray bottle, can help remove the smell of pee. You can also use an enzymatic cleaner directly on the pee stain to deodorize it.
