If you boil the Warmilu US-patented InstaWarmer pack to reset it, the time for reset depends on the elevation!

1. Boil enough water to cover pack in a large pot (a sufuria).
2. Fold the InstaWarmer(s) pack in half.
3. Place InstaWarmer(s) in pot and boil for 20-40 minutes. If you are at a higher elevation, you will have to boil the pack for a longer period of time.
4. Allow InstaWarmer(s) to cool to room temperature on a flat surface.
5. Pack is ready now for use, simply press the disk anytime between now and 2 years when you need warmth. This cycle can be repeated 100 times.

The Warmilu InstaWarmer pack can be reset and sterilized in a standard hospital autoclave cycle. The time for reset depends on the autoclave and your hospital/laboratory’s standard autoclave procedures!

1. Wipe InstaWarmer clean with alcohol wipes, or other sanitizing solution.
2. Wrap InstaWarmer in a standard sterilization pouch or autoclave wrap.
3. Set for your hospital/laboratory’s standard autoclave procedure. We recommend using a gravity cycle at 121ºC for at least 15 minutes, with a 15 minute dry time. For higher elevations (3,500 ft. or higher) in Kampala Uganda or Kenya, autoclave at 134ºC for at least 45-50 minutes to reset.
4. Remove from autoclave. Allow InstaWarmer(s) to cool to room temperature on a flat surface.
5. Pack is ready now for use, simply press the disk anytime between now and 2 years when you need warmth. This cycle can be repeated 100 times.
