I have left a PBW solution in my keg washer for up to 3 months at a time. It got REALLY funky smelling but still cleaned just fine. I dumped it so I wouldn't have to smell it anymore. I'm not cleaning sanke's anymore so it stays a lot cleaner just running it through rinsed out cornies so I think I'm at about 3 months again but it smells fine...
I mix up 1 gallon at a time & store it in 1G SunnyD jugs for when I need a little to clean or soak something. I mix up larger amounts in the FV to soak it clean.
