On the sticky theme: I had a little Bluetooth speaker with "soft touch" exterior.
Over time it turned yellow and disgusting.
I used isopropyl and lots of elbow grease to scrub it down to the base of cheap white plastic.
On screens, I have:
- Big TV - nope
- 29" 2560 x 1080 desktop monitor (not for book reading)
- Poke3 - main reader
- Nook Glow 2021 - only as emergency backup
- Shovelfuls of retired ereaders
- Moto G - quick news check, email, SMS
