A steady dry enviroment is an obvious important factor. I find that a good rub with a light oiled cloth (not leaving the blade oily as it'll attract dust and airborne particles, just removing any hand grease) and my swords are generally fine. The big enemy is the inquisitive fingers of visiting friends. Someone with acidic sweat can leave a permernant corroded fingerprint in good steel overnight.
Rub the steel with newspaper to remove any grease or dirt, then a lightly oiled cloth, then a clean cloth.
