I have 1Azrael1's yellowed '87 Targetmaster toys which I will attempt to clear up with H2O2.

Slugslinger will be the first and as you can see, he is very yellowed. I will try the twin cockpit first and the rest of the body can serve as a control so that we can check the level of improvement.



This test will likely take a few weeks or more as I use a very low concentration of H2O2 but I will post every couple of weeks to check on improvement.
