Please don’t try this if you are unsure about putting you phone in slight danger… i can’t repair phones… (Although there should not be any damage as it is quite easy) 

This is my first instructable so bear with me.

This instructable is to show you how easy it is to remove some unwanted logo’s from cell phones and other plastic / metal products. The logo has to be of the type glued onto the surface rather then etched in (which generally is the case 90% of the time) as we will scratch them off. There are many ways which you can go about this from fingernails, to pin, but there is one trick, which i have tested and will show you…

sugar.

The key is to scratch of the logo without leaving and marks on the surface of the phone (in my case PDA). Sugar works perfectly. The idea of using sugar is admittedly not my own. I first came across it on the following forum. Yet, I was not sure whether it actually works, and how to go about it. So I just decided to do it: and the results are good. Apparently the sugars -crystals are strong enough to remove the logo (sticker) but too soft to scratch the casing leaving it thus unscathed.

Whatever the reasons: it works!
