How to Use a Hair Dryer to Soften Adhesive

简介

Follow these instructions to use a hair dryer to soften adhesive. If you're using a heat gun (which emits much hotter air), follow this guide instead.

A hair dryer is a handheld device that emits a warm stream of air ranging between temperatures of 70 °F and 200 °F (21–93 °C).

Refer to your specific repair guide for detailed instructions on adhesive locations and sensitive components. Check your hair dryer's user manual for operating and safety procedures.
