I recently had a friend  point out that I am developing "Blue Moons" on my
fingernails.  Can anybody recommend a remedy?  How long should it take to
get rid of them?

I think they started when I was experimenting with CS as a deodorant and
mixed the CS with some of a "mineral stone" deodorant.  The combo has worked
great for a year or so as a  deodorant...NO odor!  Kinda bummed with the
Blue Moons...it creates a bit of a problem when I am recommending CS to
someone and they are concerned with "turning blue".

Thanks,

SS
