Abstract
A presaturated wiping product is disclosed well suited for destroying non-enveloped viruses, including the Norovirus. The wiping composition contains a first anti-microbial agent blended with a second agent, such as a preservative. Even at very low concentrations within the wiping composition, the wiping products can completely destroy and kill non-enveloped viruses at relatively short contact times.
