Sony Cybershot DSC- F828 Lens cleaning?

[gypsyheart1213]

There is residue in the lens of my Sony Cybershot DSC-f828. I know that the lens is not removable but is it possible to open it to clean the residue? There is barely enough residue to justify taking it to a camera repair store and paying over 100 dollars for it to be fixed...so any info would be greatly appreciated!
