Thanks,
Oliver

You can't - at least not permanently.

As far as I know the peroxide trick only works on white and old grey. I think
it changes the color too much on the other colors.


If you find a solution let me know, I have some older ones like this as well

Unfortunately, it only works temporarily (the bricks will usually return to an
even more yellowed state in 6-18 months) AND it makes the bricks much more brittle.
Nearly every piece I tried it with cracked when I tried to assemble them with
other parts.

Despite repeated posts on siocial media about using hydrogen peroxide WhiteBright
etc. from what I've seen and read the whitening effect may be limited long-term
and may actually make the situation worse - look on YouTube for DownUnderBrick's
video about it ("WARNING: DON'T DO THIS TO YOUR LEGO!")
