This isn’t my final ThinkPad desk setup yet — it’s still a work in progress — but I’m gradually getting everything ready. In the meantime, I’d like to share a simple and effective trick I recently discovered to restore shiny or worn plastic surfaces on palmrests and keyboards back to their original matte finish, without much effort.
All you’ll need is a standard dishwashing sponge — ideally the type with two layers: a soft foam side and a more abrasive, thread-like side. The key here is to use the rough, abrasive layer for the job. And if you don’t happen to have one handy, you might borrow a piece from your household supply (with appropriate permission, of course!). Avoid force, more time and more random movements with the sponge will result into more matte and homogenous surface of you ThinkPad's plastics. And better if you use a wet cloth to make the plastics layer wet right before you apply the sponge movements. Good luck!
