Is it appropriate to use a stack of gauze pads pre-saturated with Spec Clean˜ Ready-to-Use Disinfectant solution?

This is not best practice. Gauze fibers may interact with disinfectant agents in the Spec Clean Ready-to-Use Disinfectant solution and reduce efficacy. Reaching into an open container may introduce contamination. Gauze at the bottom may not be used in a timely fashion and become degraded.
