Left test kit outside over winter. Still good?

Got it - will order one today. I had been keeping it out by the pool all summer for the last couple of years. I guess that was a bad move too!

Test kit chemicals are heat and moisture sensitive. They should be stored inside your home in a cool, dry and dark space. A high cabinet in a pantry or wash room is fine as long as temperatures are moderate and humidity is low.

I bought a new batch of reagents last year because mine were going on their 3rd or 4th season. Everything tested the same using the old reagents so maybe run a couple of parallel tests and you may find you can use the old ones up without losing any accuracy.
