Hi EIS'ers, Stop the crap about colored bottles and light sensitivity.
I have 6 bottles of CS (3 are 2 liter clear cola bottles and 3 are 1/2 liter cola bottles.) sitting in a south window some have been there for 3 1/2 years and there is no dropout or change in color. One bottle spent a winter outdoors in Kansas City freezing and thawing. If you have drop out then you are make mostly particles and not ionic silver. "Ole Bob" :-( :-(
