If they don't get used?

I was about to put new strings on one of my guitars but I don't play it a lot.
Will the strings deaden if it's just sat there not being played?

They will corrode, although more slowly than if you played it alot. Make sure to wipe the strings after use so the sweat isn't left on the strings, corroding them.
