I've got some ColorpHast strips that I've had for awhile. Tough to use up 100 the way I brew. I've heard they have a shelf life, but can't recall what it is. Is there a way of storing them to lengthen their useful life? Putting them in a Ziplock bag with a packet of desiccant perhaps??
Or maybe hermetically sealed inside a mayonnaise jar underneath Funk & Wagnalls' porch since noon . . .
