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.
Dr. Gerba told us that he has not seen studies comparing hot versus cold water for hand-washing. Warm water might be somewhat more effective, but the difference is probably so small as not to make much difference.
