When I was at the health store getting my stone, the lady told me there that 
sometimes you have to sand off the top layer periodicallly??? Also, look at the 
ingredients on them...some of them are only mineral salts...some of them have 
added alums, etc....  I was surprised, but finally found one that was only 
mineral salts... I also use the CS under the arm too.

    I wonder what mineral salts?  I'm looking at Australian ones here.
    Deonat says hypo allergenic, Natural body deodorant. No aluminium 
chlorohydrate.  etc etc
    Freedom body says hypo-allergenic, all natural, fragrance free, ... film of 
natural minerals preventing bacteria from forming ... contains no aluminium 
chlorohydrate or aluminium chlorohydroxide
    Eon: the natural crystal deodorant ... completely pure, natural mineral 
salt ...contains crystalised Pot Ash Alum

    Sorry to be so wary of these manufacturers, but we have to take their word 
for it if they don't say exactly what mineral salts are in the product.  For 
instance, supposing someone said no Aluminium Chlorohydrate but it did have 
aluminium chlorohydroxide.  Okay, unlikely maybe, but there are people out 
there who will tell the truth with intent to deceive.  

    What is Pot Ash Alum?
