I warmed them with a hair dryer,lifted them with a credit card,removed any residue with tar removerthen applied a drop of polish. It worked without any damage but there is probably a professional alternative .Hezi
Or pour some water from a kettle, just off the boil, then carefully pull them away. Stick them on a bit of metal, glass or whatever while the adhesive is warm and you can reverse the process some time later. Regards, Don.
I used dental floss to "cut" the adhesive backing away from the badge itself. I then just rubbed the adhesive backing with my finger and it rolled off quite easily.
Warm soapy water and don't use a metal tool - fingernails made it an easy job and as said above roll off with the balls of your fingers/thumbs. Only place Volvo is written visibly on my car now is the steering wheel..... Oh and T4 on rear quarter and mesh grill.....
