Seriously? I started looking into this after I noticed that my tried and true iKlear screen cleaner acts completely different on a 2021 screen as opposed to being applied to a 2007 matte LCD screen. The iKlear spreads in effortlessly on the old matte screen, but on the 2021 screen, the iKlear smears around and feels sticky. It's a night/day difference while using the same exact cleaner on both screens. The towel is iKlear's own proprietary blue microfiber cloth. I have to admit, the 2021 screen feels like glass as I'm wiping on it. The 2007 screen feels like plastic.
