How do I remove the yellow Tarnish from my old Amiga? Or is it even possible?
That's a normal result of the plastic aging. Best bet is to paint it. You could try various cleaners, but there is a possiblity of damaging the finish. If it's safe to use on your hands, it probably won't hurt plastic. But some hand cleaners do contain solvents... the kind that craze plastics.
There is a place here that recycles computers. The owner stated that once the plastic yellows, it's garbage. It can't be recycled.
It doesn't hurt to try. I've seen A500s that smelled of smoke yet worked. Seemed it had been in a house fire... It was cleaned, but the smell remained.
Tobacco is bad. The residues get everywhere. Not good for electronics.
