Frozen cables

I had trouble paddling the other day. Pedals really hard to move, initially thought that something inside the boat was catching a cable.
The real cause was ice. The cables were wet and frozen, where they entered hull was frozen.
These are fibre/cord cables, rather than wire (which could have some lub added). 
What do people do to prevent and overcome this?

A guy I know who paddles in temps far below freezing has that issue and we were recently joking about all sorts of ridiculous solutions like steering buttons on the footplate controlling battery powered steering, and rudder lines routed along the bottom of the boat where it is warmer. He had no great fix for the problem. I have not had my lines freeze but the coldest I paddle is right around freezing and I only do that if it is a big downwind, in which case the lines are moving a ton and getting washed with water a lot. Maybe try a few drops of windshield wiper fluid from the car? should lower the freezing point a bit. 

You paddling fresh or salt water?, I would think salt would reduce freezing

Currently only able to paddle on fresh water (small river, so it gets cold quickly).

the nelo 510 has a depression in the plastic where the cables enter the hull, and water collected there. My boat is kept under cover, but we get freezing fogs here, so ice had built up on the cables and where they enter the hull (and tubing).

Responses have given me some ideas. I'm going to check if vaseline attacks polypropylene (I suspect that is what is used for these cables).

Maybe try peeing on the frozen area next time?

Great idea Zach! I could wear a Texas cath and run the tubing out through the ankle of my wetsuit! Of course I would then lose the warming effect of peeing in my wetsuit. 

I was thinking you could remove one booty and just let the de-icing fluid casually run out the ankle onto the rudder assembly, but if one leg is up on the ski then then gravity will always take the urine to the other ankle. This is getting complicated. 

Maybe plain paraffin wax rubbed into them would work.

Or even vegetable oil, or mineral oil.
