I was cleaning my 3DS XL and saw something that pissed me off. It looks like the upper screen got scratched by the touch screen. And i think it was because my sister closed it so fast that you can hear like a clap. It looks like this Warning: Spoilers inside! *This is not my picture* But its vertical all the way on the upper screen. Is it possible to clear that somehow? What chemical can i use to clean it? I tried with the polyester cleaning cloth but it didn't help,it did but just a little.
