Before attempting to remove the remaining adhesive from the glass, use a grease pencil or permanent marker to mark the original location of the mirror. Make the mark on the outside of the glass so you do not remove it when cleaning off the adhesive.
Use a razor scraper to remove the remaining glue from the glass. Place the edge of the blade on the glass, and continue scraping until the surface is smooth again. Leave the mounting plate attached inside the bracket on the mirror, and use the scraper to remove any remaining adhesive.
Wet a lint-free cloth with isopropyl alcohol, and wipe the inside of the glass to remove any dust remaining after scraping the adhesive. Use a hex key to remove the mounting plate from the mirror, and wipe the plate with the alcohol cloth. Allow the alcohol to evaporate completely before proceeding to attach a mirror to the glass.
