Blanket Safe Professional Horse Blanket Wash and Deodorizer is a cold water wash that is detergent-free. It is low-sudsing, residue free, and has built-in deodorizers. This horse blanket wash not only gently cleans your blanket of dirt, but the bacteria and grime that cause gross odors! It will not ruin or deteriorate your factory applied waterproofing, although it is recommended that you re-proof your blankets after the first two seasons of use. This detergent-free wash has no harmful chemicals, making it very safe for sensitive horses and can lower the risk of further skin issues. A 33.8 oz container will wash 4-5 loads depending on soiling and load size.
