Whitening yellowed toys with Hydrogen Peroxide

[Galvatran]

a day in the sun shouldn't have a lasting effect on any plastics really. but if you're really worries, perhaps masking those parts is the way to go.

also, I'm not sure if you need direct sunlight for the h2o2 to work, UV happily passes through clouds.

This is one of the greatest threads of all time
Thank you.
My G1 is nearing 100% so I want to have it look amazing.
I have a couple of G1’s that I’d like to keep but they only have a little bit of yellowing.
Through respect I’d rather show respect to the 30 + years of a toy than just replace it for 50’ish $.

So yeah, thanks once again for the great detailed ideas.
