...
    Can someone point me to schematics for a decent
homebrewed demagnetizer?

You could try using a degaussing coil, it's used to
un-magnetize picture tubes, might work on small parts.
Find a junked color TV (bigger the better) and take
the degaussing coil out of it. Twist the coil to loop
it into a small 5" or so circle, add a power cord, and
wrap the stacked layers of the coil in tape. Don't
leave it plugged in for more than a couple seconds
though! It's not intended to be powered for very long.
