Is washing your hands with cold water equally as effective as washing your hands with warm or hot water?

Yes, yes it is.  Water temperature doesn't effect how clean your hands get (and if any of you start talking about increased molecular velocity with increased temperature, Ima hit you for being obnoxious and making a meaningless argument).  


Here's the reality - water has to be very hot in order to have any sterilant properties.  In fact, it has to be hot enough that, were you to have it contact your skin, it would burn you.  If water isn't hot enough to burn you, it isn't hot enough to kill off any kind of 'germs'.

What will impact how clean your hands are is how effective you are with scrubbing your hands - this is why surgeons have a fairly specific protocol of how they wash their hands.  The whole procedure is to ensure thoroughness.    


So, if you want clean hands, choose a water temperature that is comfortable and then be very, very thorough with the scrubbing of those hands.
