Hi,

Can anyone tell me what metal is used in the 1986 light and sound electric parts.
I have just acquired 2 sets from the space classic series and they are seriously
yellowed. I want to identify what metal is used and if I can soak the parts in
Hydrogen Peroxide, as its the only way I know to remove the staining.

Thanks

Tom

Hi there, Hydrogen Peroxide will turn the metal black and impede connectivity,
cheers, James.
