I always dealt with ice in the guides by popping it out with my fingers.
Last winter I finally tried chapstick and it worked great. I applied it once at the start and it lasted the whole time I fished. Just don't gunk it up in the guides because I would imagine that would be a drag on the line shooting through the guides. Also, it's alot easier to pop ice out of snake guides as opposed to single footers.
