As somebody who doesn't care too much about the appearance or colour
of the machines in my collection, the only reason I would try to de-yellow
something is if it prevented further deterioration of the plastic (not the colour,
but the fact that some plastics turn very brittle with age, for example).
I do not believe retrobrite does this (does it?)
I don't know of a treatment that does, is there one?

I'm leaving mine alone (and not just because I am lazy). It would appear you
can use retrobrite at any time, but you can't undo the effects of it. So I'll
keep my machines as they are (unless there is some treatment to
prolong the life of the plastic), if some future owner wants to deyellow them
after I am in a pine box, they can.
