The idea behind it is to use a sugar cube to scratch off the stickers on the cell phone. The sugar should not leave a mark on plastic or metal. Process with the following steps at your own risk - in the worst case, you could damage or leave a scratch on your phone.
- Place tape around the area you’re going to scratch. This is important because you don’t want sugar to get in the phone.
- Scratch the sticker with a sugar cube until it has disappeared completely. Repeat until the cell phone looks clean.
- Remove the tape and clean up the remaining sugar with a dry cloth.
If all went well, you will have a clean unbranded cell phone, with those pesky stickers from your carrier gone forever. Apparently, this trick will not work on some cell phone covers though - the sugar cube will leave a mark.
