My parents recently finally decided they can return me my childhood toys with 1990s Technic sets including the 8880 Super Car. All other sets were in boxes, but this one spent the last 15+ years assembled in a clean attic, so it's dusty and yellowed, but surprisingly, complete (I disassembled it with the instructions in hand). I haven't yet decided if I should keep or sell it, but I need to clean it.
Question: This piece.
I've read about bleaching LEGO bricks with hydrogen peroxide and about removing labels for repair. Do you think it's a good idea to remove the labels and then bleach the brick? Or is there some other, better way of helping this guy?
