Hi Nick, congrats on the great guitar. I would try contact spray first. Hopefully you can get Deoxit. You shouldn't have to remove the switch, just make sure you immediately clean off any spray that may inadvertently get on the finish. Not a panic but you should clean it off. By the way, I don't know how I missed this thread before, but I own a first gen 5420 and a new FSR a couple of months old. They are both great guitars and the difference wouldn't make your eye water if it got stuck in your cornea.
