I am about to try retrobrighting my very mustard yellow A1200 and also the Keys.
I am doing the full immersion type. I have found a large plastic container and ordered about 4 litres of 12% liquid peroxide. Next up is buying some uv lamps.
Hope this goes well.

Edit: I am now finished and the result is way better than What i expected. It looks brand new. I ordered 8 liters of hydrogen peroxide. I found a large 55l container that i wrapped in aluminumfoil around the outside. I had to attach a heavy spanner under the chassie to keep it submerged and I had it in there and under uv-light for about 24 hours. Same thing for the keycaps. I just poured them in and turned them upside down and let them float around in the peroxide for 24 hours.
This is a very good way to go since i was afraid of marbling.
