I use that stuff a lot too when I'm repairing electronics gear like my
old Tek and HP scopes. They still recommend alcohol and the non-clay
based paper as the means to clean gold contacts though.

It is amazing how much grub it get off connectors, without harming the
plating at all.

You really don't want to use an eraser on gold plated contacts. The gold
plating is quite thin, and the eraser will wear it away. Much better to
use alcohol and something like a coffee filter or non-clay based paper to
clean up the oxidation. Especially on the female contacts where you will
inevitably leave eraser residue. Once that's accomplished insert and
remove the card into the slot several times.
Erasers have fine grit mixed in with the rubber and act just like
sandpaper. Not good for gold plating.
