Medline ReadyPrep CHG 2% Chlorhexidine Gluconate Cloths are designed to reduce the risk of surgical site infection, also known as SSI. This product can also be used to bathe hospital patients to prevent skin infection, especially for people who use urinary catheters. Each pre-saturated cloth quickly kills bacteria such as staph, E. coli, and more. These CHG cloths reduce microorganisms on the skin for up to six hours after application. They are fragrance free, rinse free, and measure 9" x 10.5" to cover a large surface area.
