Today’s microwave makes heating the Heartwarmer much easier. Heat the entire bag on full power for approximately 2-3 minutes. Some microwaves may take a minute or two longer. You will soon discover the exact time for your microwave to produce a comfortably hot Heartwarmer. Remember, the Heartwarmer may get very hot. If it feels too hot, let it cool for a few minutes before using it. You may wash your Heartwarmer slipcover just as you would any pillowcase. Do not attempt to wash the Heartwarmer itself as water will damage the contents. You may notice a roasted scent as you warm the Heartwarmer, this as well as a moist sensation will lessen after extensive use. This in no way diminishes the usefulness of your Heartwarmer. You may also place your Heartwarmer in the freezer and use it as an ice-pack.
