The Laundry additive is a liquid solution that kills viruses, bacteria, and fungi on a large scale and a broad spectrum. It is Bactericidal, Virucidal (both enveloped and non-enveloped), Fungicidal, Tuberculocidal, AND ANTI-ODOR. It works by producing a 99.9% Kill rate. It is Non-Toxic because it has been declared not harmful to humans. Once applied to your laundry during the wash it will remain active until your next wash. You simply wash your clothes the same as before, just add the laundry additive to your last rinse cycle. Then dry your clothes in the dryer or air dry and achieve an antimicrobial layer on your clothes once they are completely dry.
