Lay the iOpener clear-side down, flat on the edge of the device, over an adhesive seal you wish to heat. The liquid will flatten the iOpener against the surface, ensuring good heat conduction.

Let the bag sit on the device for approximately 90 seconds before attempting to open the front panel.

At this point you should be able to begin prying under the screen with a plastic opening tool. Be sure to see your device's specific guide for where and how to do this.

During the procedure you may need to reheat the iOpener. To prevent overheating the iOpener, always wait until the iOpener has cooled enough to touch safely. Do not microwave the iOpener for more than thirty seconds at a time.
