It seems to disappear with sugar cubes. Although it was not actually tested, it is unknown whether it really disappears, but the review that I tried actually went up overseas. What kind of mechanism is it, is this?

The way to do is as follows. A commentary movie is also put.

How to remove Logos from your PDA / cell phone with sugar

※ If you execute the following contents at your own risk.

◆ What to align
· With logo such as mobile phone and PDA
· Cuban sugar some
·Tape
·newspaper
· Pin (needle)
· Cloth (for wiping off sugar later)

First lay the newspaper and place the mobile phone on top of it. Then close the part other than the logo with tape. This is to prevent sugar particles from entering inside. Then, rubbing the logo lightly from the top with cubic sugar is good. It is easy to use horns. Since there are movies that actually cut logos with cube sugar in the above-mentioned review article, as a reference. It seems not to be too strong or weak. Also, it will take quite a while. Furthermore, there are cases where sugar melts and sticks with the heat of hands, and the tape protecting the vicinity seems to be damaged first.

But in the end it has succeeded in scratching the logo intact. Those who think that the corporate logo is an eyesore, may also consider by self-responsibility.
