Eliminate foul odors on your boat, in your car, or in your home or office with this safe, natural formula that works for up to 90 days. Unlike traditional air fresheners that cover up odors with masking fragrances ("fresh linen, apple, cinnamon, etc.) Fresh Wave’s formula actually breaks the bonds of odor molecules, rendering them inert. Fresh Wave Spray is easy to use: Simply spray on fabrics, surfaces, and into the air to eliminate odors almost immediately. It's as easy (and safe) as spraying water.
