So I see greasy finger on my Apple 23. Not knowing and I'm a complete noob I spray a little bit of windex on a cloth that come with my display and start wiping it. I learn later my Display is not glass and you're not suppose to use Amonia on it. I just got a little bit of Windex on it. It is ruin? it is damaged? I check and check but I don't see any harm done. But I still have 5 days left to return or exchange it. Should I take back and get a new one? But I can't tell them that I use Windex on it. What to DO?
