lewis,
Loctite do a super glue remover that you could try!
or Acetone (nail polish remover), but be careful as it can dull dark surface laminates!
Personally I would use one of those small Dremel type sanding disks to chip away carefully most of the glue off first, then use the glue remover in one or two stages while wiping with lint free or microfibre cloth, then use a plastics scratch remover to polish!
lets us know how you get on!
