I called the Public Health Department and got the official answer.
They have a disclaimer about "check the expiry date" before mixing.
I found a 3M report that the loss can be 50% at the end of a year. Public Health tells people to only buy what they need in the short run.
The reality is that they use test strips to measure the actual concentration. So health inspectors will check how the mixture is made, they measure, and advise.
