Open the lid of the Nintendo DSi. Place a soft cloth on a table. Place the DSi on the cloth.
Blow off the scratched LCD using bursts of compressed air.
Moisten the end of a cotton swab with petroleum jelly. Place the moistened end of the swab against the LCD screen and to one side of the scratch.
Lightly press the swab against the LCD screen. Push the swab along the length of the scratch. Remove the swab from the LCD screen as soon as you reach the other side of the scratch.
Place the edge of a microfiber lens cloth against the LCD screen and to one side of the scratch. Lightly press the edge of the cloth against the screen. Push the edge of the cloth along the length of the scratch. Remove the cloth from the LCD screen as soon as you reach the other side of the scratch. Turn the DSi on.
Inspect the LCD screen to see if it the scratch is still visible as the DSi's opening graphics play across both screens. If you can still see the scratch, repeat the entire procedure of applying petroleum jelly to the scratch and wiping the scratch with the cloth. Turn the DSi off when you are satisfied that the scratch has been fixed.
