IPhone :: Can IKlear Remove Oleophobic Coating On IP 4?

my friend told me the iKlear I was using the clean my phone removes an "oleophobic coating" (which I have never heard of before) on the screen. Is this true? If it is, don't you think should say in big red letters "DO NOT CLEAN SCREEN"? Or maybe, iKlear shouldn't advertise a product that can damage an iPhone 4 as "iPhone safe". I got the really expensive user-damage Best Buy warranty because I have had horrible luck with my iPhone and iPhone 3g (take amazing care of them, no scratches or anything, but I drop it once after a couple of months of proud ownership and it shatters everyone else seems to have super phones because they can drop it repeatedly with no problem).so if the oleophobic coating was taken off I just need to pay a $10 restocking fee to get a new one. Is there any way I can tell if it was taken off? It does finger print, but it's not like it didn't before I cleaned it.
