In a study of 20 healthy volunteers, hand wiping with or without an alcohol-based solution was found inferior to hand rubbing with an alcohol-based solution in reducing microbial contmaination on hands. The authors concluded that this finding warrants a note of caution for the application of wipes in health care. The study can be found at: Ory J, Zingg W, de Kraker ME, Soule H, Pittet D.
