Removing the badges is straight forward.
First, clean and wax polish the general area around the badges to reduce the chance of scratches. Then apply heat to the badges and body surface to soften the glue, then use waxed dental flossing tape working your way under and across the badge. Then polish the now de-badged area and ensure all traces of the glue have been removed from the body surface.
Heating the glue.... you can either use a hairdryer or pour hot water on a microfibre towel and lay it on the badge and refresh it a couple of times with hot water.
There are also lots of videos on youtube.
