I used something called Fastrac. There are 2 parts, a little metal slide that you put a cloth sleeve on to clean the track, and the lube. It works amazingly well after application. I can haul the main on my Tartan 37 without the winch
. You have to run the slide up and down the track to clean it,, then change the cloth sleeve and apply the lube. Make sure you have a good downhaul on the cleaner!
