It must be something in the air. Maybe sailing season. I'm working through the seven winches on my E32-3 right now for the first time. They're all Barient self-tailing: 27s, 23s, 17s, and a 19.
I use kerosene and a toothbrush to clean. A few hours soaking seems to do the trick. Sometimes a flathead screwdriver to lightly scrape the real gnarly bits. 3-in-1 oil on the pawls and Harken winch grease evenly and lightly on the other moving parts, gears, bearings, etc. Using the workbench at home is far easier for me too.
Whoever serviced these winches last before me seemed to put grease on everything, including the pawls
Similar to others, I could barely turn a couple of them by hand.
