Arm & Hammer Pet Fresh is a baking soda carpet powder for homes with pets. You sprinkle it on dry carpet, let it sit 15 to 30 minutes, then vacuum. The baking soda neutralizes pet odors trapped in the pile, and the brand says its Vacuum Booster helps the vacuum lift about 25% more dirt than vacuuming alone. It also targets smoke, mold and mildew smells. It suits carpeted rooms where a dog or cat leaves odor, and it is a low-effort add-on to regular vacuuming rather than a deep cleaner. Rivals in this category are mostly enzyme or fragrance-based powders; this one leans on baking soda and a light fresh scent.
