Basically, I've used all of the above, and perhaps a few more (including meths). I've found that when dealing with old, coagulated grease slathered on before I owned them, none of these solvents is terribly effective! They're OK with grease that is still soft, but old grease dries to a hard, varnish-like consistency and I've found that no solvent really touches it. My brother had a go at them with a car degreasing setup, which circulates hot caustic soda solution and that has been more effective.
Moral of the story - REALLY only use the smallest smear of the appropriate lubricants!
Useful tip I was given to deal with old caked on grease was to only partially disassemble the winch, soak the grease in 3-in-1 then go out and do a few races (I guess as a non-racer you'll have to do some hectic crusing to simulate the winch usage cycle). The grease is then softer when you disassemble the winch a second time.
And finally, for the OP: believe it or not, diesel is about the cheapest solvent available for cleaning winches.
