Oil stain on iPad screen

I used a moisturizer on my hands that had coconut oil in it. Coconut oil may be rumored to cure mostly everything but it does not help your iPad screen! I’m kicking myself for not taking a “before” picture so you could see the ghost of my fingers pressing the screen. Thanks to someone’s answer, I tried a little Dawn soap on my finger and let it sit for a few minutes. It looked like it was working but rest of the screen had a film so I used PLEDGE MULTI on a paper towel and pressed a bit harder and IT WORKED!! My screen is now an oil free zone. Thanks so much to these forums. They are priceless. So it’s really great that they’re free!
