Title:	Disinfectant delivery system and method of providing alcohol free disinfection
Abstract:	A disinfectant delivery system and method of providing alcohol-free disinfection to a body to be disinfected, as well as a method of infection reduction by preparation of a patient before an invasive procedure. A blended cloth comprising first fibers and second fibers is provided with the first fibers generally being greater in quantity by weight than the second fibers. A disinfectant solution impregnates the blended cloth, with the disinfectant solution having chlorhexidine gluconate as an active ingredient and having no alcohol. In the method according to the invention, at least one impregnated blended cloth is used to disinfect at least a portion of a body. A plurality of blended cloths can be provided for disinfecting discrete portions of the body. When an invasive procedure is to be performed on a patient, a further method according to the invention of infection reduction comprises using a CHG-impregnated cloth to disinfect at least a portion of the patient at least one day prior to the invasive procedure proximate the location of the invasive procedure.
