If you don't have a microwave, follow this step to heat your iOpener in boiling water.

Fill a pot or pan with enough water to fully submerge an iOpener.

Heat the water to a boil. Turn off the heat.

Place an iOpener into the hot water for 2-3 minutes. Make sure the iOpener is fully submerged in the water.

Use tongs to extract the heated iOpener from the hot water.

Thoroughly dry the iOpener with a towel.

The iOpener will be very hot, so be careful to hold it only by the end tabs.

Your iOpener is ready for use! If you need to reheat the iOpener, heat the water to a boil, turn off the heat, and place the iOpener in the water for 2-3 minutes.
