So I haven't touched my DSL in a loooong time. Decided I better dust it off (literally) so I went about cleaning the screens and the outside of the case. I've got a problem though. It seems some sort of liquid has spilt inside the glossy part of the case and it seems impossible to clean. It's also managed to get itself under one of the shoulder buttons. Anyone know how I'd go about cleaning these places? The shoulder buttons themselves have gotten a bit darker from use too. Should I think about maybe buying a new case or something? I've never case modded before, but I'm sure I could do it if I had to. Cheers!
