I can see why you added that last bit - do not under any circumstance
use emery cloth, isopropal alcohol yes but not an abrasive. Many
plug-in-boards like the graphics card in the Iyonix are coated with a
ultra thin (microns) coating of gold to assist conductivity and
corrosion resistance and can easily be damaged/removed using an
abrasive. You might have more than pyjamas to cope with after
subjecting PCB edge contacts to this sort of treatment. This is a
definite no-no with the latest high speed PC graphic cards.

Just a polite warning.
