Only the top right looks like it "needs cleaning". But really, no cleaning is needed, since they are all legible. Rather than increasing whatever value (not a lot) they have, stripping the three AE's that still have their original Patina will turn them into Culls. The top left, as already mentioned, has no Patina left and so that one has nothing obvious to clean off.
