I started a religious war about 20 years ago on this list with this,
but here goes: ;-)

I like Pink Pearl erasers (rubbers in English).  The Pink Pearl has a
titch of abrasiveness, which helps remove oxide or grunge from contacts
without being agressive enough to remove metal.  I use a tissue
dampened with a drop of wd40 and wipe the contacts.  The wd encourages
good contact and bars oxide formation.
