I keep mine for about 3 months or until I have spilled too much too much for it to be usable. I've heard much longer.

I use RO, not distilled.

thanks! I've heard until it gets cloudy, but just getting some other thoughts.

Actually, cloudy isn't a good indicator. Some water sources will cause it to go cloudy near instantly. A true test would be to measure the ph.

For kicks? Or just to test it?

Wow! Mine's pretty grungy-looking after 3 or 4 months, so I usually dump it then. But I don't doubt you've gone that long. pH has never been an issue for me.

I don't start testing pH with strips until it gets cloudy. I use RO and keep in a sealed bucket in a closet in the house, to avoid the big temp changes in the garage. Usually lasts up to a year before I mix new, unless the quantity gets low enough to need it sooner.

Kinda by accident.  I had some mixed up in a spray bottle and forgot about it.  When I tested it, it was still good.

Yeah, I got some low range strips that are used for wine.
