Restoring Yellowed Plastic

[Super]

Interesting. I would imagine it depends on what caused the yellowing. Do they have a video of the procedure they used? At first look of the picture the yellow doesn't look like it was from the sun or smoking because its too even all over and I am not so sure the original color was white or the cream color in the after picture. It also looks like they had to have completely dismantled the machine as all the stickers and the burgundy parts don't look to be affected at all by the hydrogen peroxide. However it does look like the pictures are actual as if you look at the circled area it looks like the inside of that tunnel is yellowish. I would like to see how the procedure went.
