Those stickers usually catch on something and start coming off on their own after a few months of use. I would simply use my fingernail to gently pick at a corner until it lifts off. I've dealt with some older stickers that have gathered dirt and dust in the adhesive residue and a bit of rubbing alcohol is gentle enough to not leave any signs on the surface finish. I'm not too sure about the rubberized finish standing up to the alcohol for too long but a quick gentle wipe probably won't hurt. Test it out on a less-noticeable area first just to be sure.
