Chemicals intended for use around electronic components, including PC
boards, have been formulated according to an industry-wide "Non
Aggression Agreement". This aims to ensure that chemicals such as flux
cleaners and contact cleaners will not damage the plastics that are used
in the majority of components. In return, component manufacturers try to
avoid using plastics that would be damaged by solvents in common use. 

Undiluted acetone is not part of that agreement because it's simply too
aggressive, as Fred describes. 

Although electronics-grade solvents are more expensive than bulk
commodity solvents like acetone, for peace of mind they are worth the
extra cost.
