Instructions
Open the DSi lite so that its two screens are flat.
Rub the top screen using an eyeglass cleaning cloth. Repeat this process for the bottom screen.
Wipe the screens with a damp cloth, if they remain dirty after cleaning with an eyeglass cleaning cloth. Allow these screens to dry thoroughly and wipe the white plastic of the DSi with a clean cloth.
Close the DSi.
Rub the outside of the DSi with a clean, lint-free cloth. Rub the outside of the DSi a second time using the eyeglass cleaning cloth.
Remove the game from the DSi's game port. Hold the DSi so that the game port faces sideways. Hold a can of compressed air so that its nozzle is several inches from the DSi's game port. Pull the trigger of the compressed air to clean out the DSi's game port.
