Boiling Instructions

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.

Autoclave Instructions

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.
