Honestly, I stopped messing with alcohol sprays because they can strip the oleophobic coating off some glass screen protectors over time. If you want that fresh out of the box feel, grab a Whoosh Screen Shine Cleaner kit. The chemistry is non-toxic and it doesnt leave those annoying streaks that happen with DIY mixes. I usually pair that with a thick, high-density microfiber cloth like the Apple Polishing Cloth. It sounds like a meme, but the weave is actually different from the cheap ones you get for free with glasses. The key is really about pressure. Use light, circular motions and try not to press too hard, or you just push the oils back into the microscopic pores of the protector. If you get smudges, just dont touch your screen right after eating snacks. Seriously, that makes the biggest difference tbh.

To maintain a pristine iPhone screen protector, I use a microfiber cloth dampened with a 60% distilled water and 40% isopropyl alcohol solution, gently wiping in circular motions. Regular handwashing reduces fingerprint buildup, keeping the screen clear.
