A Note on Hand Cleaners...

     I read a fascinating article on hand cleansers today (free subscription may be necessary to read the article).  It turns out that not all alcohol hand cleansers are created equal.  Buying tip: make sure that the alcohol’s concentration is between 60 and 95 percent.  If it is less than that, it won’t do the job.  Indeed, it actually just pushes the germs around instead of killing them.  The study doesn’t knock alcohol hand cleaners; just make sure you use a good one, and use enough: “If your hands are dry within 10 or 15 seconds, according to the C.D.C. guidelines for health care workers, you haven’t used enough.”
