yellowed murky plastic

[Curt at Atari Museum]

I have a friend who is a major Mac geek (infact his license plate is 
macgeek) and he used to fill his tube up with cleaning solution and soak 
old Mac cases and Apple ][ cases for days on end to reduce the 
discoloration.      It all depends on the reason for the discoloration - 
some are from heat, cigarette/tar residue, others are from sun UV 
exposure and others were from just the grade of plastic and color 
mixture (I used to pull virgin Atari ST's out of there boxes and find 
them discolored, I noted this with some of Apple's platinum line of 
computers during the "Quadra Years" that the plastics would discolor 
just from the quality of plastic.

Some of the discoloration can be superficial while others go right to 
the core of the plastic parts.
