Once the pack has given off all of its heat it will remain in a crystallized harden form until it is recharged. To regenerate your click and heat pack, place it in already boiling water and continue boiling for a period of 5-10 minutes (do not allow vinyl coating to touch the pot or bowl directly), or until all of the crystals have melted back to a clear liquid state . You may notice bubbles, this is normal, carefully remove the pack with tongs from the water (watching you do not burn yourself do not pick up directly with your hand) and place on cooling rack and let cool to room temperature before reactivating. To speed the cooling process, place the click and packs in the refrigerator. NOTE: The click and heat pack will not reactivate if its temperature is above 130° degrees F, cool time is mandatory for reuse.
As long as you do not break the stainless steel disc, there is no limit to the number of times a pack can be used.
