I have no problem keeping the screens clean, and the glossy parts clean, but whats bugging me is the matte areas. Oh the outter part of the DS Lite, the exposed matte areas to me seem like are turning yellowish, could be the light though, but it doesn't seem like its as white as it was when i first got it. Also, it seems like its getting dirty. I don't really know what to use to clean it with, I've tried alcohol, but that didn't work still looks kinda dirty. What do other people use to clean their DS Lites with? Also, just a side note, I have a crack in my left hinge, been there for a while, was thinking about getting a SHOCK! case, anyone know if their cases are alright quality wise? I've heard they're just the clear casses with paint on it, lol. Thanks.
