Card reader head cleaning

I wouldn't use anything more abrasive than paper to clean the heads, with maybe a tiny drop of alcohol applied on the cleaning side, then just give it a couple of swipes in and out the left side of the slot. Does that sounds like a safe way to do it?

So far the card reader is working fine, I'm just planning ahead in case the heads get any oxide buildup.

Cleaning solution on same side as magnetic surface of card - facing downwards.
Sounds ok

Years ago when I worked for the telephone company we used to have to clean relay contacts with thin strips about the same size as the magnetic cards. These had a micro brush surface on both sides which would be ideal for this purpose.
