Oxi Blast is a professional urine product. Previously only available to professional cleaners and odor removal technicians. It is now available to you. It works by forcing large amounts of oxygen into the urine residue breaking it down into basic elements like carbon dioxide, oxygen, nitrogen and other elements. These compounds then leave by evaporation or are easily extracted. This product is a specific blend effective on urine not only because of the oxidation but it also contains odourcide, an odor neutralizer that attacks the dog urine neutralizing it by bonding to and encapsulating it. Oxi Blast works on eliminating the urine odor in two separate ways. The oxidation is also affective in removing the urine stains. Plus it contains additives that enhance solution penetration to improve rinsing and removal. The last item I am going to mention is that they have built into it anti-resoiling properties that keep the treated area from attracting new residue. You can order a free sample here. They do charge a shipping and handling fee.
