I've heard that if you rinse with 4.0 water right before storing, the PH won't fluctuate much.yep i use the super budget varieties. cause they are cheap i buy 2 and i alternate between them and often use them both to compare them to each other. as long as you rinse them in clean water after every use drift isnt too bad.
Next time I calibrate, I'll save the 4.0 and try it.
