Card reader head cleaning
What's the conventional wisdom on keeping mag card reader heads clean? I know there were some special purpose "cleaner" cards provided back in the day, but what's available now that's safe to use? Can I just snip a piece of an index card to roughly match the size of a mag card, and feed it through a couple of times? Maybe give it a very light coating of 99% isopropyl alcohol first?
