hi i have a dsi and i was playing it last night before i went to bed (i was playing nintendogs) but i must have fallen asleep on it and rolled over on it. i woke up later and put it away but in the morning i looked at the screens and they were all dirty! i tend to have slightly oily skin, so they must have gotten oily when i rolled over on them. otherwise, i don't know how it happened, but they just looked dirty. I used my mom eyeglass cleaner thing first, but that thing's a piece of crap and it didn't do anything, so i kept on trying, but the stuff stayed there. later i tried some of out soft toilet paper, and it worked fine on the top screen, but the bottom ones all messed up now. i'm afraid i've made it worse. i don't want to try anything wet because i don't want to wreck it, but i just don't know what to do because it really bugs me. any advice? plz answer soon. thx!
