How do quats work?

A quat's positive charge actually helps it bind to bacteria, viruses and other microorganisms that cause disease—all of which have a negative charge. By doing this, the germ's cell walls are disrupted, which ultimately leads to its destruction. To completely disinfect or sanitize a surface, quats must be in contact with that surface for a certain length of time. This time varies depending on the product and application method, so always double check the instructions on labels.
