Storing in the door of the fridge is worse than you think

Practice › Storage & stability cold chain beyond-use date storage freeze-thaw cloudy or discoloured solution temperature excursion

Solved

Solved by KAndersson in post #2

The opening post is the version of this I will quote in future. One addition. What is reasonably well supported: refrigeration slows degradation, repeated warming and cooling is worse than either state alone, light exposure is worth avoiding, and adsorptive losses matter more in dilute solutions.

Storing in the door of the fridge is worse than you think Writing it up because I had to work it out twice and would rather nobody else did.

Asking about the failure mode rather than the procedure, because the procedure is documented and the failure mode is not.

I know what I am supposed to do. What I do not know is what it looks like when it has gone wrong, and by the time something is obviously wrong it is usually too late to learn from it.

So: what does the early version of this mistake look like, and what would you check first?
