Once mixed and activated with vinegar, how long will a bleach+water+vinegar solution last? Will it degrade over a few hours, a day, a week, a month? Assuming I mix this up using tap-water for big jobs, how long will it last?
What about DI water as is recommended for starsan longevity?
Currently I mix it up every time I brew and keep some in a spray bottle for non-brewing use. I replace the contents of the spray bottle each time I mix it, it never looks cloudy but I don't know when it stops working.
