I have a huge lot of yellowed Lego's, I want to try to de-yellow them. I have searched around the internet and this method seems the most promising:
I have a few questions about this : - What is happening at the surface of the ABS plastic ? - My knowledge on this subject is very limited, but would the process go faster when you perform the process in a ultrasonic bath ?
A bit of unrelated question : - Is it possible to combine the de-yellowing with filling any scratches gaps in the bricks ? It seems not to me because you have to have some filler in the solvent or break the bonds in the lattice, i guess ?
any help, information is welcome, I'm like to learn new stuff !! I can only understand it a little bit from a nanotech point of view.
