After it cools, simply drop the pack in boiling water for a few minutes and it’s ready to be used again.Toasterz non-toxic active solution can be recharged almost indefinitely. And it’s so safe, it will leave only a bad taste in the mouths of any kids (or kitties) who manage to break its ultrasonically sealed pthalate free vinyl package. *Never use Toasterz directly against skin to avoid heat burns, a light towel or cloth is all you need and you conserve heat so Toasterz last longer too!
