This is a commercial strength water based deodorizer. Pro’s Choice Air Fresh leaves the perfect amount of fragrance after cleaning or in between cleanings. Strong enough to be effective on such odors as mildew, dog dander, water damage and many more but light enough to not overpower small areas. Pro’s Choice Air Fresh is available in “Lemon”, “Cherry”, “Fresh & Clean” and the new “Crisp Apple” and “Tangerine”.
