Didn't HP specify something like this when servicing the card reader on a 97 to verify that track length was within specs?

Magnasee
It deposits minute iron particles on the magnetic surface so probably renders the card useless and abrasive.

I used Magnasee back in the day with digital tape drives.

I don't know if this would work, but for $3.95 it may be worth a try.
