Hello!
I bought an old tamagotchi angel, the package must have been stored at a sunny place, the shell has a little bit yellow discoloration from one side. Its minimal but I'd like it better without discoloration. (I know, i have ODC^^)
Does anybody know how i could remove the sun discoloration?
I currently try to cover the area with a hydrogen proxide 3% damp cloth.
In reality it's worse like in the picture:
