So i found what i thought were micro-scratches on my ipad pro after cleaning it with alcohol and microfiber clothes (car wipe, not glasses). I was pretty bummed with it since i only used pencil and my fingers on the ipad and people said pencil wouldnt scratch the ipad. I tested the pencil on a tempered glass and it didnt scratch so there is no way the pencil could scratch it. But turns out these micro scratches can be wiped clean with my finger... Is it the oil from my finger that disguised the scratches? Or are they simply dust and i just did not clean it enough? If its the latter then how do i *really* clean it?
