MarkI'm no expert on this procedure either... but I do recall hearing that Tobacco/Caramel Cards (with litho images) respond much better to soaking than glossy modern cards with photographic images.
I have a Cobb T-206 that would likely benefit from soaking. It has residue from mounting corners, and is otherwise EX/MT. But I am scared to death to attempt soaking, and would definitely practice with lesser valued commons first.
