I know lots of folks have done this, but here's a few shots of the RetroBrite process used on my keyboard keys and the before/after on it. I use a very simple 3 ingredient recipe that I can mix in 4 ounce batches for tiny stuff. The case itself cleaned up really good with some Greased Lightning and a magic eraser, there's a few nicks left but nothing to really be worried about.

The before and after is pretty significant on this one!

Here's a shot of just one key I tested with about 45 minutes of time in the sun, the rest of the keyboard got about 6 hours.

The stuff I mix:

Last thing I want to do is make/acquire a 128k emblem for the keyboard panel.
