sorry if this is old hat.
most of the googling shows cleaners to remove dirt but none of
these products actually reverese or remove the yellowing i find
in some off white plastic parts?
I have tried things like peroxide washes and , tuff stuff
cleaners to no avail.
can yellowed plastic be rejuvinated ?
I am guessing it is sm chemical rection that has occured ? and
will require some chemical reactin to restore ?
anyways any helpful info greatly appreciated,

Yes, it's the typical effect of polymer's degradation,
especially for PC.

i'm sorry but when i read your post i was harried so i
read "ruined" instead of "rejuvinated".
Your plastic degradated so i think you can do anything,
or however i'm not able to help you.

I don't believe you can remove the yellowing.
You may be able to make it less objectionable
by coloring it with a very dilute blue dye.
Many types of laundry detergent contain blue
dye to make the whites seem whiter. In years
past, it was sold separately as "bluing". |
