If you never open the can, It will last almost forever. If you open the can every day, You might get a few months... Shelf life is relative. Having a good seal on the container is key as well. I use a mason jar with a clean lip. If I feel it is not sealing good, I pour into a new mason jar. I have used many different clears and KBS is the best I have used and really have no reason to try anything else.
