That b*llcks, white spirit is fine and does a great job of remove glue residue, i used it on the rear badges and bump strips with no hassle or paint removal.
Id disagree using a heat gun as its very easy to apply too much heat and the paint will bubble, which wont be reversible. I have used loads of methods because my were such a pain in the arse to remove.
What i prefer is apply Hot water to the badge, then get some dental floss underneath the badge and pull it along until the badge comes off. If any glue is still on there i used an old credit card to scrape it off. Then followed by a bit of white spirit on a cloth rubbed across the surface to free up anything left under there, i used the credit card again if anything was on there. Clean the surface then T-cut it, perfect! nothing visible at all with no indication of where the badges were.
If you amazing managed to spill half a gallon of white spirit onto the service then let it dry

Then hard work with the T-cut would get it out.
