CDS Expiry

Dear friends
Does anyone know how long CDS will remain good if stored in the fridge.
I recall Jim saying at the begining that CDS will remain ok for about 2 months in the fridge.
I made some in (I think) about January or February and it still seems fine.

Thanks
Colin

Hi,
Colin

Yes if the dark and in a bottle with lid tightly closed to not escape the gas.

LOL, you'll know it's "gone" when the solution is clear with no color.

Great Thanks.
It is still quite dark so I guess it is still good.
So in my case, CDS lasted over 4 months stored in the fridge in a plastic bottle that is well sealed.

Much appreciated
Colin
