I'm sure many of us here have more than one guitar. And there is probably one or two guitars that you play less. Or at a minimum, even if you have 4 guitar, and even if you use them equally, that means each of them isn't used 75% of the time. Therefore, I was wondering, when it comes to maintaining your guitars, especially for string life, how do you store them? Do you keep them in their cases? Hanging on a wall or on a stand? Do you use string lubricant to protect the strings? Also, I've read here that, though there isn't a concensus, it seems most people will change their strings after 5 to 10 hours of playing. But, even when the guitar rests on a stand for days, strings will somehow wear down (since it is in contact with air, oxygen, and air humidity) and though they will obviously last for more than 10 hours, you can't leave them on eternally, even if you never touch the guitar. At some point you'll change them. So how long do you wait before changing the strings on a guitar that you don't use too often?
