Reversed Osmosis water for making and mixing MMS1 for consumption

I've used all kinds of water, including chemically treated tap water and brownish water from streams out in the woods. I can assure you any water that is reasonably clean will work.

I certainly would use the water you got there.

The very best water likely is properly distilled water. It would make the end product most effective.

Water can in fact spoil and then it will not work. It will not even work to make citric acid. I know that because I've used so called sterilized water, and also de-mineralized water for car batteries. Both work very well usually, but these products do spoil over time and render it useless.
