I've just bought a second-hand 23" ACD and there were 3 stickers on it, 1 on either side on the glossy plastic, and one one on top.
I managed to lose the glue on top with an iKlear wipe and some elbow grease, but the ones on the sides wouldn't budge.
Hastily
o) I grabbed some nail polish remover (propanone) and daubed/rubbed a spot on the side and then wiped it off, but it soon became apparent that the top 1/4 of the panel has now lost its glossy laquer where it was rubbed, as it is smoother, duller and streaky 
(I know propanone's a solvent, it was stupid but I wasn't really thinking!)
Does anyone know a way to one, get rid of the glue from the second side panel without damaging the plastic, and two, if there's a way to repair the damage to the affected side? It's hard to see but I'd really prefer for it to be fixed.. Thanks!
