This is the UN-Scented version of the popular Natures Miracle 3-in-1 Odor destroyer in the larger 946ml bottle. The 3-in-1 products and the lavender Stain and Odor Remover are the only Natures Miracle products that work to eliminate the difficult airborne, hard surface and fabric odors. This product has received glowing reviews because it works by actually neutralising odors by surrounding them rather then temporarily masking them like many other products do. The advanced triple action, bio-enzymatic formula breaks down and actually destroys organic odors in the air, carpets, kennels, tiles and other hard surfaces. Works best when allowed to dry naturally and it is especially important that the product reaches all of the affected areas.
