So in a matter of days, our nano had many scratches, including deep ones on the screen and even more on the central button.
So it was our pleasure to accept testing the polishing kit called iRenov
It contains a leaflet, two pots of polishing pastes and 3 synthetic clothes.
You'll first use the paste "deep" of higher granulometry, which will take care of deep scratches, and create even more superficial ones.
Our advice is that you first push firmly, then go on softly.
Once the paste fades the iPod nano has many superficial scratches yet the bigger ones will disappear. If not, just go on polishing.
Then, use the finishing paste of thinner granulometry. First rub it strongly, then softly once again. The more you'll stay soft and patient, the best the result.
In 10 mn, we reached this result:
Some thin scratches remain to be seen only by rasing light, and the biggest disappeared. A more elaborated care would undoubtedly give even better results.
