Removing Adhesive Residue From Grooves
Protect the reflectors/decor panel by taping over them with paper and masking tape.
Allow the adhesive to cool in the groove a bit so that it is easier to remove.
Cut the adhesive along both sides using tools 9997067 and 9997066 until the surface in the groove is somewhat even. Even out any adhesive residue that is left using a hot air gun and chisel.
