Many studies have been conducted to evaluate hand washing techniques.[1,4] The following general observations were noted: â¢ The use of 3 to 5 ml antiseptic soap was sufficient; more than 1 ml non-antiseptic soap did not enhance cleaning. â¢ A washing duration of 5 to 30 seconds can be effective.
For proper hand washing, all you need is 20 seconds and some soap and water. Here's how to do it: 1  Wet your hands with clean running water (warm or cold) and apply soap. 2  Rub your hands together to make a lather and scrub them well; be sure to scrub the backs of your hands, between your fingers, and under your nails.
