William --

Having been on a few (!!) pelagics and having had my binoculars 
salt-encrusted many times, I'll offer some pointers. If you have truly 
waterproof bins (high quality Zeiss, Leica, etc.), salt spray will not be a 
problem. Just thoroughly clean the body with a damp towel or old tee-shirt, 
using tap water, when you get home. If they are really bad, do the cleaning 
multiple times, each time with a clean towel. Towel dry to finish. The lenses 
should only be cleaned with soft cotton or special lens cleaning fabrics and 
lenses cleaning fluid or water. You might also want to take the lens cap off 
to do a better job of cleaning the lenses. The biggest risk is scratching the 
lenses while cleaning, so be real careful about this. Try to blow off any 
large particles. You can imagine a piece of salt dragged across the surface 
of one of those multicoated lens finishes! If you have top-quality bins and 
faith in your manufacturer, you can hold them under the running facet to 
clean, but I've never had the nerve to do this. My 10 year old Zeiss 10x40s, 
which are supposed to be sealed, now develop internal fog during very wet 
conditions.

I you have less quality bins, you need to be very careful about getting them 
wet at all, but the basic cleaning procedure would be the same.

Generally on pelagics, I would suggest using a rain guard on the lenses, as 
the spray will accumulate and blur your view. Also, depending on how rough it 
is (i.e., if there is heavy spray), I would recommend keeping your bins tuck 
inside a half-open jacket. This is how I normally do it and it works fine. 
Also on a really wet trip, your hands can get very salty, and it is good to 
periodically clean them with a wet towel. You can also do interim cleanings 
of the bins then as well.

Another way to achieve the same result (and protect the rest of your bins as 
well), is to hang a small hand-towel (say 5 x 12") over you bins (half the 
towel in front and half behind, with the fold over the eye pieces). This 
protects both the lenses and the body. When the puffin flies by, move the 
towel to one side.  

Good luck,
