How important is a clean screen?

Is it worth paralysis?  Nerve damage?  If you happen to own an iPhone, that shiny glass screen that greeted you in the box may have indirectly caused just that.  According to a new lawsuit filed in China against Wintek, a supplier for Apple and other tech companies, 44 workers have asked for compensation after being forced to clean glass screen with a known toxic chemical, n-hexane.  While the line manager who made the decision to use n-hexane has been fired, little has been done to help the workers who are now suffering the effects of such a truly stupid choice.  

The reasoning for all of this?  N-hexane dries faster and leaves fewer streaks than alcohol.
