I'm varnishing down below. All the small SS butt hinges on all the doors are in good shape, but a bit gummy and they open & close a bit stiff. The years of Watco oil on them from oiling the teak doesn't help. What's the best way to clean them up ... a little soak in lacquer thinner, vinegar ? Clean them up with wire brush or Dremel ? They certainly seem worth saving ...

thanks, cheers, John
