H.S. BLUE is specifically designed to be used in porta-toilets and recreational vehicle restrooms to reduce suspended solids and eliminate odors with its pleasant cherry fragrance. H.S. BLUE digests and liquefies organic waste, grease and food by-products. This product easily eliminates odors by breaking down the molecular structure of odor sources. Unlike conventional deodorizers, H.S. BLUE is not a perfume mask that covers up odors. It has the unique ability to attack odor molecules and neutralize them.
