The second spray in the spray-wipe-spray procedure is used to disinfect the surface. The first spray wets the surface and the final spray ensures that the disinfectant remains on the surface for the appropriate contact time. Disinfectants can only kill germs if they are left on the surface for the recommended amount of time, so this second spray is critical for ensuring that the disinfection process is effective.
