Thanks guys. I meant locally as in somewhere common (i.e. Lowes, Home Depot, Walmart...) I currently use a 1:10 Bleach solution, but would rather use something safer.

I do like the idea of a 6 month diluted shelf life though. That alone might push me over to the F10 camp. From what I've read, the Chlorhexidine should be used within a week of mixing... And I don't think the Bleach solution is much better.
