1. Vinegar-Baking Soda Spray
It doesn’t get much easier than this spray. Most of the time, this is the one I choose to use. It’s simple, inexpensive, and works a treat on blood and urine stains in particular. White vinegar is a miraculous substance that will get rid of even the old accident stains that might have been missed if a dog did a “ninja-pee” behind the bookshelves or something. Baking soda is nature’s odor remover, and teamed up with vinegar, does a great job at getting rid of odors!
