To ensure a good adhesive bond, thoroughly clean all adhesion surfaces.

Use adhesive remover or isopropyl alcohol (>90%) to remove any remaining residue. Wipe with a cotton swab or microfiber cloth until all the adhesive residue is gone.

While isopropyl alcohol is generally safe to use on electronics, they will dissolve certain foam adhesives. Be careful to contain the alcohol when cleaning—don't use too much.

Allow any leftover isopropyl alcohol to completely evaporate before reassembly.
