Does ZYTREL XP have any residual efficacy?
Yes, whereas traditional alcohol-based sanitizers stop working immediately after they dry, ZYTREL XP has residual efficacy and will continue to work for up to 4 hours after each application. Of course, that does not mean you should wait 4 hours to reapply it. You can use ZYTREL XP repeatedly, safely and effectively as necessary, throughout the day.
