I have it in a spray bottle and has lasted until I used it up... about 6 months.
As long as the pH of the solution is at 3 or lower it is good.

basically forever as long as you use distilled water.

It can react with the minerals in tap water and degrade over time, so use distilled for your spray bottle.
