Not really true. 99.95% pure is available but expensive.
Not quite sure if available in small quantities. It is available in big
drums with excellent purity.
Slightly less pure but perfect for contacts is also
Another option would be to use acetone.
NEVER use acetone unless you are sure of the encapsulation material. It can
chew quite a number of epoxies and plastics. Although CPUs have a ceramic
substrate, the metal heatsink to ceramic bond is epoxy.
