Primos Silver XP is a Dual Action product eliminating both bacteria caused odors such as body odor and nonbacterial odors such as smoke and food odors. Primos Silver XP works on contact and instantly removes odors from clothing and equipment and keeps them gone for up to 24 hours. Before the days of refrigeration, old timers would put a silver dollar in a quart of milk to stop bacterial growth so the milk would last longer. Today, Primos has invested in a patent pending technology utilizing tiny particles of suspended Silver in a scent eliminating solution so hunters will have the most effective means of combating every type of odor. The Colloidal Silver particles in Silver XP strike bacteria before it has a chance to break down and cause body odor.
