This isn’t a comment on gunk existing or not existing. I understand people’s issue with the gunk. It’s merely a comment showing that it can be easily cleaned with some alcohol wipes and a good microfiber cloth. (I used the one that came with my iPad)

It took me 5 wipes (alcohol evaporates quickly after all) and about 15 minutes and I have a perfectly clean screen with no scratches.

Be patient and use the proper tools and it will clean up just fine.
