Default Yellow aging stains

I recently acquired a rare plastic model that has yellow aging stains, probably from sun exposure. Anyone know how to remove or lighten without ruining the finish or printing? Is it even possible?

It is possible from what was shown on the DAC. There have been a few threads the past year outlining steps on how to make yellow go back to white for the plastic models. I will see if I can dig them up for you, later today or if another DAC member can provide the links. Cheers! T7

Came across this one:

https://www.diecastaircraftforum.com...cs-models.html

I thought there were another 2-3 threads on this topic as well.

Thanks for the links. I'm just worried hydrogen peroxide will remove the titles. I'm not sure if they're tampo or decals. I'll try it on the stand first.

Plastic is an oil-based material and oil is naturally brown, so white plastic will turn cream in time and even oil-based white enamel paint turns cream in time.
A repaint with acrylic paint will solve this issue.
