I have an old R4A that has severely corroded coper plate on top, even  
some rust spots on the top of the chassis.  The underside looks brand  
new and the radio still works fine in spite of the ugly chassis top.

The problem is caused by pollutants coming in through the 'holey'  
cabinets.  You can plug the holes (not recommended) or stop showering  
the radio with pollutants.

It is nearly impossible to remove corrosion once it sets in.  Use of  
cleaning products could turn a working radio into one that does not  
work anymore.  I would leave well enough alone and cover the radio  
with a plastic bag when not in use to help prevent future corrosion.

Yeah but that equipment did not have any exposed electronics, did it?

I know the 'knob polishers' go nuts over a little discoloration.  My  
approach is to avoid fixing things that are not broken.  That T4X is  
worth about $160 as is.  Were it not corroded at all it might be worth  
$165.
