Big odors show up in small spaces. Fortunately Fresh Wave Fresh Pods go anywhere. Garbage cans, closets, diaper pails, lockers, boats, RVs and more! Take the refillable case out of the plastic pouch and peel off the adhesive backing. Adhere to a clean, flat surface*. Those small space odors are cut down to size! Replace the Pack every 30 days with Fresh Wave Odor Removing Packs.
