Two old computer mice turned yellow over the years and needed some brighting up. To achieve this we are going to use the retr0bright method.
For this experiment we are going to restore old Amiga and Atari ST computer mice. As you can see they became yellow by being exposed to sunlight.
I am not sure about the origin of the Zydec mouse as I bought it together with an Amiga 500 computer. But actually the mouse can be also connected to an Atari ST computer. On the bottom of the mouse there is switch.
First we need to create some retr0bright creme. In this blog I have covered in detail how to prepare it.
Put the solution on all the parts that need to be whitened, cover it with microwave foil and expose it to UV light for 36 hours.
The internals of the mice are still in good shape, so after the plastic covers are restored, they should look as new.
As you can see, the difference is quite large. The zydec mouse is almost white and the Atari ST brightened up a lot. I believe that second treatement would improve the results even more.
