Polish is probably not a good idea for a matte finish. I think a damp soapy rag is good, followed by a cloth dampened with clear water.

Whatever you do, avoid furniture polish, or car-care products! They often contain silicone, which can contaminate any shop that works on your guitar. A paint job on a silicone-contaminated guitar turns into a mess of 'fish-eyes' because paint will not grip on silicone. And there's no such thing as a solvent that will get rid of the stuff!
