what works great is get a ds cleaning cloth or just a glasses cleaning cloth, or just a gaming systems cleaning cloth because they are all made of the same fabric. Just give your ds a rub with one of those and your good to go. My sister has a black ds lite and she and I both got gamestop PSP cleaning cloths for our ds lites and they work perfectly for our ds lites. It feels just like a glasses cleaning cloth and it works wonders! You can find a cleaning cloth at gamestop, EB games and of course online stores or a glasses store, or probably walmart or target for the glasses ones. Good luck and happy holidays!

the outside: use a oily rag then a dry rag (both clean) the inside: a dry cloth then buy some extra screens at any game store thats what i do on mine and if you are planing on getting a ds lite buy one withclear colors not dark cuz then the "dirtyness" will be "less"

Well, my freind had one. He said that you must carfully take a dry cloth and take out as much as you can. no matter wat DS you have, be careful to not snap it. He had good luck with his DS. Be careful though.

The dishwasher works well for mine.
