lube the track all the way up
anything that will absorb water, e.g., rag, small piece of sponge, etc..., attached to the halyard and a downhaul, soaked with lube will work. If you have an old slide or car on which you attach the material and which fits into the slot, it makes life alot easier. I normally soak a sponge and run it up/down the slot with the headcar a few times. Don't forget the masthead sheaves which is another story...
