That's not good. I bought a further 2 bottles in case they try to stop us buying it. It will probably take a year to use the one bottile i've got.
I guess you can tell if its still good if it turns yellow and gives off the chlorine smeell when activating. Maybe it just becomes weaker with time rather than stop working completely, heres hoping anyway.
I think Jim advised against storing it in the fridge b/c of the light exposure it would get from people always opening & closing the fridge. From my understanding, the #1 killer of this solution is direct sunlight....and the #2 killer is any light at all....makes me wonder why they didn't put the solution in copletely opaque bottles vs. translucent ones.....and why they picked green bottles vs. brown....brown bottles tend to block UV rays while green bottles don't.
1) Since it is sensitive to light, wrapping the bottle in aluminum foil or something similar would benefit. Then refrigerate.
2) Several people are adding drops to their drinking water, including me. I normally don't drink an entire glass of water in one sitting. I carry it around with me, to remind me to fill it again when done. This will not be good for the longevity of sodium chloride in the water.
Great idea about wrapping the bottle in aluminum foil...I'll do that with mine...just keep in a place where any child cannot access it. (I have a 2 yearold...best to keep it away from him)
I don't think that dropping the MMS in drinking water will have any MAJOR benefits other than purifying the water itself...and if you are just using it to purify the water, then the longevity of it shouldn't matter. Once it has killed what needs to kill in the water, it can safely go away....as long as you don't re-contaminate your water...which unless it takes you days to drink a pitcher of water, would be hard to do.
