Neogen's line of Dairy Hygiene products for clean-in-place and bulk tanks includes both alkaline and acid detergents as well as specialty products for residue and build-up. These products are manufactured in California and Tennessee to maximise freight efficiencies. Tetradyne® dairy chemicals are formulated to keep your milking equipment clean and residue free. We offer a variety of strengths that can be used in combinations of daily use and shock treatments as needed. During seasonal changes, our technicians can recommend products to use before you see a problem. Using the alkaline, acidic and sanitising products in combination, as recommended, will help keep your equipment bacteria counts low and your milk quality high.
