MoldGuardian™ is currently being used By Pfizer, Amgen and Celgene, to name a few, to remove mold from their operations and to prevent and keep any new mold growth from contaminating their environment and operations for at least One-Year. All natural “Generally Regarded As Safe” (GRAS) ingredients make it safe and easy to apply by spraying, fogging or wiping. MoldGuardian™ is excellent for ventilation systems. Once applied, MoldGuardian™ dries and becomes water resistant, continuing to be a new spore growth barrier that prevents any mold growth on a treated surface for at least one year.
