can i use lens cleaner spray to clean my ipod

Apple recommends against uing lens cleaning fluid because it will remove the oleophobic coating on the glass causing your fingerprints to show more.

The recommend cleaning fluid is to slightly dampen the microfiber cloth with pure water only.

It's not on their recommended list

Carefully, so it doesn't get between the screen and the metal shell. Better if you spray the lens cleaner on a microfiber cloth and use the whetted cloth to clean the screen.
