One-of-a-kind formula. State NO Contest was specially formulated to provide maximum protection for your drain system. Its formula consists of Neem Oil, extracted from the seeds of Neem trees, and five strains of bacteria, forming a clinging gel. The Neem Oil allows NO Contest to coat the surfaces of your drains, covering the accumulated biological matter where drain flies flourish, while the bacteria works to breakdown and clear the buildup. NO Contest also contains enzymes that will treat drain systems with regular cellulose buildup. Due to its gel-like qualities, NO Contest can be applied wherever organic matter, proteins, starches or grease persist, even in vertical applications. Its highly effective formula is ideal for use in a variety of applications, including floor drains, beverage tower drain lines, restrooms, portable toilets, garbage chutes, dumpsters and more.
