I think only once essentially. I suppose you could use it for a few days then put it back in a ziplock bag to store for a while, but the ad says it's only good for a couple months in the plastic, so I imagine it won't last forever. I've considered just keeping the bag and refilling it from the granules that you can buy in the cannister for a lot cheaper.
