Mainly on the front, the screen side. How do I do it? I'm away from home, I'm 14, and I have no way to get an eyeglass cleaner from CVS or the likes. I also forgot my black Touch cleaner. What can I do? I can wipe the touch on this shirt (which is VERY soft) & it goes away a little, but in a few minutes a bunch of finger trails go across the screen, even without using the touch (it's locked, charging). Any ideas for a quick solution?
