OK, we get it. Sometimes life can be more fun when you get a little dirty. Not in this case mate. Do yourself and the world a favor and clean up a bit! Grab a cloth and get all that oil and nacho sauce off your stuff before you apply your new skin. You'll thank us later.
 
Moral of the story...if your device is dirtier than your browser history, it's time to scrub a dub dub. Just think how many people are going to awe in glory at your new skin. Don't you want it to be free of gunk and yes, we said it, fecal matter. Don't be that guy...or girl...or person. Whatever, clean your junk before you skin it!
