The Nintendo DS is a pretty hardy piece of machinery, but it never hurts to treat all your electronics with care. Here are some basic tips for keeping your Nintendo DS in tip-top shape.
Keep a microfiber cleaning cloth handy.The Nintendo DS screens, particularly the touch screen, have a way of collecting dust and fingerprints. A microfiber cleaning cloth (the kind you use to clean glasses lenses) will keep your screens beautiful.
Be gentle with the touch screen.Some games will tempt you into pecking furiously at the touch screen. Still your hand until you're sure you can use reasonable force. The Nintendo DS is hardy, but it has its limits.
Don't use foreign objects on the touch screen.This includes keys and pens. A bad scratch can mess up your Nintendo DS permanently. Use the stylus only. Indulge in some fun themed styluses at your local game retailer. There are lots!
Buy a carrying case.If you plan on taking your Nintendo DS everywhere, it's worth considering a sharp carrying case to keep it clean, dry, and free of the horror of getting banged around in a purse or backpack.
Store your games carefully.The days of throwing naked cartridges on a shelf are long over. The Nintendo DS's game cartridges—called “cards”—are tiny things that are easily lost, swallowed, or knocked under a couch. Always keep them in their cases when they're not in use.
