Screen protector surface coating

Anyone notice that the surface oil-repelling coating seems to wear off very quickly on the protectors? Causing grease to build up on the screen very quickly…

Also, Anker how do we clean the screen and not damage the layer further?

Can’t say I’ve ever noticed an issue, but then again my phone seldom gets more contact than my trouser pockets.

Best method I’ve found for cleaning is spectacle wipes / spray cleaner.
