Sailkote is not Teflon! It is a mixture of white paraffin wax doped with Dupont Krytox, which is a great-grandson of Teflon. Krytox is damned expensive stuff, a good lubricant which simply doesn't break down under extremes (-70F to 700F, sulphur, chlorine, oyxgen impervious, etc.) but they mix it in with white paraffin because the wax disperses it and keeps the cost way down, compared to the pure stuff.
Your best best is to first CLEAN THE SAIL TRACK, nothing will help more than that. Often you can find a foot of rope or dock line that can be jammed into the track with an uphaul and downhaul, run it up and down a few times to clean out the crud. (Or a rolled rag, whatever fits snugly in the track.) You may want to soak that in kerosene or WD40 or soapy water to help it get going.
After the track has been cleaned--use the Sailkote. There are also similar products sold in bicycle stores as chain lubes, same ingredients for the same reasons since the wax+krytox also won't stain white sails--or pant legs.
The wax eventually wears away pretty much clean, without trapping more dirt the way a grease product would.
