How long does sodium meta bisulphite last in a spray bottle?

[Leeboy]

I usually make up,a spray bottle full and spray tools and stuff, I'm wondering if I could store what's left or do I just throw it away each time ?

I think that if you can smell the SO2 it is probably good.

I use mine till its gone. Usually a bottle will last me 2-4 weeks depending on how much wine I have going. If I'm not sure, I spray it in my hand a take a whiff. After I come to, I get up off the floor and keep sanitizing.

I've probably gone as long as 3-4 months in my spritz bottle and it will still have the sulfur dioxide smell. I'll dump and make a new batch just to be certain. Do like LoneStarLori does and you'll be good to go.

I've had a smaller amount than what is in my spritz bottle being used in a rubber gasket sealed 23L cork-a-dore, its been several moths now, and when you pop the lid the fumes are obvious and very strong.
