Does MMS solution expire Does activator solution expire

I have two bottles of mms and activator solutions - do they expire? They are less than one year old

It should be still good to be used.

You can activated it and see if it does turn dark yellow brown during activation.

What is your activator for MMS, citric acid or HCL?

They should be good for 5 years if kept cool and away from light. As Edwin says, you can always make a MMS1 dose and look for a color change and the usual CLO2 aroma.

Thank you
it does turn brown but has a cloudy/murky look - In past it appears more clear with color -odor seems to same as when I used it 5-6 months ago
