Retrobriting is a way to whiten plastic that has turned yellow with age. It uses hydrogen peroxide and light, and results can vary with the plastic, so it suits a case you are ready to risk. Opening the machine and removing boards, labels and rubber parts comes first.
The 8-Bit Guy tried it in 2013 in an early test, and returned to it in newer techniques. Hey Birt puts the claims side by side in a myth-testing video. Noel's Retro Lab compares sunlight and liquid peroxide on an Amiga 500, and that maker is sponsored.
Strong peroxide burns skin and eyes, so gloves and eye protection matter. Ultraviolet lamps harm eyes as well. Keep both away from children and pets, and work in a ventilated space.
