Does it get very warm in your garage? Perhaps you could find somewhere it stays a little cooler to store your cs. Make sure its in a light proof jar. I like to also fill the jars to the very top to allow as little room for air as possible. I don't really think the air would hurt it much but that's what I do and my cs stays good for at least 30 days. If it sits longer I just make more and dispose of the old. I'm sure it would still work but its so easy to make I would rather not take a chance on wasting time.
I used distilled water and 14 gauge silver wire.

It does get warm at times since I live in so cal.
Arrowhead was the brand. And purity was. 9999 and it came with a cert of some sort.what distilled water ? some people mistakenly think the distilled water for topping up car batteries is ok , but its not , even if it somewhat works
what purity wire ? and can you be sure your source is legit/honest ? it only has to be something like 96% for them to call it pure
mine has been stored at way above room temp in the past with no colour change
im baffled , ive never seen or heard of it turning blue before
peace
I was just sayin about temps because I know that high temps can degrade cs but I haven't ever heard of it turning blue either. Are you sure its not grey? Maybe the lighting in the room made it appear blue?
