iPod Touch 5th Generation Cleaning

[lancebtaylor]

While repairing an iPod Touch 5th Generation, I got some fingerprints and skin oils on the red parts of the picture. What is a safe way to remove it without damaging any of the electronics?

Dirt there will not be an issue. Those locations are not critical. Cleaning can easily go wrong and I don't really know what you can use besides a dry cloth, it is probably safer to not clean
