Hey Faith,

I have used my homemade CS I had stored for 4+ years and it has worked as well 
as my freshly made CS.  I do this once in a while to try to see how long the 
effectiveness lasts, and to rotate my stock so to speak.  For what it's worth, 
my old stuff worked as well as the fresh did for me and other family members 
and friends.  I always keep LOTS (sorry no scientific numbers as to how much) 
on hand, some of it several years old, as back-up in case of emergencies.  It's 
very comforting to know that my 4+ year old CS works as well as my fresh (in my 
experience - more years in other peoples experience) in case I need it down the 
road.  Hope this helps some.

Ruth

  Dear indi:

  Thank you very much for your efforts.  I think, after all, that you are 
  right about anecdotal evidence. I appreciate the fact that you are 
  discussing this.  Truthfully, I have wondered about the condition of CS when 
  stored for a while,  and wonder how much it has changed, and what its 
  present condition is.  I personally cannot afford to get lab analysis on 
  older CS.  I wish I had some guidelines as to how long to keep it before 
  chucking it and making some new.  Thanks again.  Faith G.
