The clear screen on Mary’s ZZR400 was really showing its age when we bought it. It was incredible misty, scuffed and well, just not very clear. Ideally, we’d like to swap it for a nice gloss But in the meantime I went at it with some Meguiars PlastX polish. This is a fancy plastic/acrylic polish with microscopic abrasive particles, designed specifically for all kinds of plastics. Perfect for lights, screens, I even used it to good effect on my turntable lid!
Its no good against deep scratches, but it will sort out tiny scuffs and get plastic looking shiny, glossy and transparent again.
As you can see from these before-after shots, it has made quite a difference. I’m sure if I removed the screen and polished up some more it would look even better.
