Well, it seems my hands are naturally quite sweaty or perhaps i've been playing ds with dirty hands ... A while ago playing my DS lite i realised the d-pad was getting a bit sticky. Taking a closer look a noticable darkish stain was aound the dpad. It makes playing a bit unpleasant (i use the touchscreen as often as possible) i tried carefully cleaning it with a wet cloth, to no avail. has anyone else had any problems with sticky/stained d-pad? Any reccomendations on how i should attempt to clean it?
