Whitening Yellowed ABS Plastics Whitening Yellowed ABS Plastics Hot

Rather than replace or paint those old yellowed ABS plastics on your game, there is another solution.  Using a simplified version of the Retr0Bright technique you can make them look like new.

In Images 1 and 2 you can see a typical yellowed shuttle craft from Star Trek the Next Generation.

Get a zip lock bag, fill it with 3% hydrogen peroxide and a spoon full of Oxiclean.  Mix until the Oxiclean dissolves.  Put your part in, make sure it is fully submerged and put it out in the sun (see Image 3).  Rotate the bag occasionally so all sides receive sunlight and it should look good in a few hours.

Images 4 and 5 show the final result.  Pretty amazing.

You can get a white bloom effect if you leave the plastic in the sun too long.  See the link above for more info or for mixing the exact RetrOBright solution.
