Why 70% EtOH for cleaning?

Hi all,

I have a very general question.  I was told that 70% EtOH is more effective
than 95% EtOH for sterlizing and cleaning surfaces.  Tradition of course is to
use 70% to wipe hoods etc.  I had assumed 70% was used just to cut costs. Can
anybody out there tell me why 70% is used? Just curious really.
