Blanket Safe Professional Horse Blanket Wash and Deodorizer Ultra is a cold water wash that is detergent-free and super safe with its harmful chemical-free formula. 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. The ultra wash has added deep cleaning properties and anti-static to help remove excess hair and prevent cross contamination of those blankets being washed in communal machines.
