Just a hypothetical, but could it be the wearing off of wax on frequent touch points (ie. the wax is over the entire screen, but wore off where you use the screen the most). It might hurt more than help but maybe a wax stripper could fix this?

Looks like Evfred nailed it. Isopropyl alcohol on a soft cloth and I'm about half way to a "new" screen working up from the bottom...

Like I said above, live and learn! Just water and microfiber from now on!
