Wettability of hands during 15-second and 30-second handrub time intervals: A prospective, randomized crossover study

Based on our results, a 15-second application time is equal to 30-second application time in terms of wettability of hands. The improvement of wettability after training underlines the necessity to instruct new and untrained health care workers in hand antisepsis. Using fluorescent handrubs may be a feasible method to control and retrain hand hygiene techniques of long-time employees.
