Cleaning Look labels etc.

I have a naked carbon 2001 KG281 with the gray Look labels.

I'd like to clean off what little dried grease etc. if possible. Is there a safe method of doing it without damaging the labels?

Also, is it necessary to put some type of treatment on the naked carbon for protection.

I have read where some riders apply something to the frame - I don't want to change the shade too much if possible.

Thanks in advance.
