-> TW> A good old fashoned Pencil eraser I have found does a much better job.
-> TW>In fact in my day of repairing Critical Medical Equipment several
-> TW>manfacturers recommended Pencil Eraser cleaning of card edge
-> TW>connectors.

->  Many of us in GEMS used to finish the cleanup with a light coating
-> of TV tuner contact cleaner to leave a small deposit of oil in the
-> small pores of the metal contacts to delay corrosion resulting from
-> the salt air here on the right coast.

 Actualy for hte medical equipment they recomended leaving the Contacts
Dry. The Chips had a tendenacy to work their way out of the sockets
anyhow with the Heatup/CoolDown cycles. 
In fact Reseating All chips was part of the Quarterly PM routine.
