You can try to scrape them off with a razor blade or sand them off. Either way you will need to finish with a fine grit sand paper and buff it out. Go easy and try to keep all the scratches in the clear coat, and you'll br fine.
there are soooooo many multiple ways of debadging a car in general.
sanding however is unnecessary and would do more damage to the paint than u have to.
easiest way is to do it on a hot day, when the cars been sitting in the sun or get a heat gun to warm up the glue of whatever badge your removing.
for a large badges i find dental floss or even a razor blade (carefully) work well. make sure you take your time, no rush, and you wont damage the painted surface. the sticky residue and glue left behind can easily be taken off by a bug/tar remover cleaning product on a rag. even a lil "Goo-Gone" or those sorta chemicals too, but im not a big fan of them cause you have to be careful, not to damage the clearcoat of the paint too much.
good luck with your debadging
