IPhone 5S official case: how to clean them?

How do I clean the official iPhone 5S cases if they became dirty? Can I use alcohol pads? Or will that remove the color?

And thank you.

I don't believe that alcohol will remove color, but I would avoid something that has acetone, like nail polish remover, as that would possibly remove paint. I would also avoid any product with chlorine bleach.

if there are embellishments glued onto the case, I'd use nothing stronger than baby wipes, since you don't know what the glue base is.
