Remove rearview mirror adhesive by marking the original location of the mirror, using a razor scraper and cleaning the surface with isopropyl alcohol. Clean both the glass and mounting plate before using a kit to attach a new base to the glass.
- Mark the location of the mirror
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.
- Scrape away the excess glue
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.
- Wash with isopropyl alcohol
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.
