I'm not a huge fan of logos though I can just about live with the tiny 'Nokia' on my phone. Still, on the occasions when you really must get rid of those loathsome marks, here's a sweet way to do it. Get yourself a few sugar cubes, tape off any holes where you don't want the granules to penetrate and start scrubbing. The abrasive nature of sugar will get rid of most logos. It works on the same principles as sugar soap (good for walls and kitchen grease) without being wet.
Please note - it doesn't work on plastic and if you are at all in doubt, don't don't do it! [Via Propellerhead by way of Instructables]
