I recently purchased some beige TIs off of craigslist. I cleaned them up and they still had a bit of yellowing so I had this great idea to retrobright them. It was a big mistake.
The retrobrighting process turned them white, and the process also left the coloring marbleized. For reference, I did not retrobright the keys; also in the photos, the TI sits on top of a white freezer. I did die a little inside after I saw the results
It is entirely possible that I did something wrong, but I just thought I would share my experience in case someone else has the same great idea. It might give you a little pause before you do it.
