How to clean cubes?

[LexCubing]

I have a Gans 356 White and what's a good way to clean it w/o damaging and also I want to sticker a new?

I don't have that specific cube, but generally I just take the cube apart, and wipe off all the pieces with a paper towel. As far as stickering, thecubicle.us has a lot of sticker options.
