Antiseptics are used on the skin or mucous membranes. They reduce infection risk by disabling or reducing number of micro-organisms on the skin. They are used on both the health care worker and the patient.
As with other disinfectants, you must follow the manufacturer's instructions. For maximum effect, observe specified contact time.
Choose an antiseptic suited to the specific purpose. For example, in surgical use, consider body site and procedure:
Hand wash/scrubs act against bacteria on your hands. You should choose one that immediately reduces the number of organisms and also has a residual effect.
