I was just wondering how long a bottle of water conditioner will last after it is opened?

I thought I was saving money by buying a large bottle, but at a drop a gallon it is taking a while to use it all.

Should I replace it after six months or a year? or just be sure and keep it in a cool, dark place and make sure the cap is on tight?
 
Ive had bottles of prime last for years.
