I was looking for a good method of re-moisturizing bud that had gotten too dry. I'd read about adding apple or orange peel, putting a wet cotton ball in the container, etc. All seemed to have drawbacks I didn't like: danger of moulding, favoring, or otherwise damaging the stash. One morning as I was burping the canister with one hand and steaming the milk for my latte with the other, it occured to me that sometimes the left hand ought to know what the right hand is doing. I put the cannister under the nozzle and gave the bud a really quick shot of steam -- as fast as I could open and close the valve. Problem solved, instantly!
