My take on this:

I've found that stuff stored for a long time builds up a coating of
dust and gunk (oil, grease?). Better to use a solvent cleaner on the
chips and sockets than shove the crud back into the socket.
I wouldn't use a screwdriver--take some scrap steel or aluminum sheet
metal and use it to make an "L" shape. The length of the horizontal
part of the "L" should be nearly the length of the chip and about
2/3rds the width of the chip between pins; the vertical part should
be long enough for you to use it as a handle. Slip the leg of the L
under the chip and gently rock it from side to side using the
vertical handle until the chip pops out. You're much less likely to
bend the chip pins this way.
Pencil eraser on the gold fingers on the card edge
too, until they are
nice and bright.
If you have to use an eraser, use a gum-rubber one without the "grit"
most pencil erasers have. Better just to wipe the edge connectors
with a contact cleaning solution.
My .02 anyway,
