    Been sailing since before I could walk (initially not of my own volition). Most of us have photographed the things we love at some time or another. Got any images?

    Oh re the filters; being somewhat acquainted with the problem that you have on a regular basis, I agree with the plain, clean water suggestions.
    Or you might go with charcol micro-filtered, distilled, PH neutral, UV blasted but untouched by human hands variety if you prefer and you have some handy.

    .... and don't rub them until they are clean of salt residue for obv reasons.

    Best, john.

It's more important to get the stuff off quickly in the freshest water you have available.

    Well as I work in glass, I have learned to carry 'clean' water with me, for those times that it required.

    The cleanest water available may be more harmful that the water that has contaminated the filter..

    Just my obeservation after several years of shooting in mineral laden water areas..

    Looking at it from the perspective of someone who is expected to deliver the most clean glass that I can, I will take the extra precautions to ensure that my lenses and filters are as clean as possible.

    Because evaporation will leave a residue of any disolved material. In practice, if you dry the filter well with a lens cloth this will be minimal. Some disolved salts might also damage the coating.

    Thank you all for the very informative responses. I am sure there are others that this simple but valuable tip can assist in their photographic adventures.
    After dunking in warm distilled water, leaving it for half an hour then moving it in cold distilled water for a bit, I shook it for the excess water to come out then wiped it with a lens cloth and left it to air dry.
    It looks fine now.
    Thank you all!
    I was out and about the city shooting since my brother stole the jeep and I was vehicleless for a longer excursion, I found myself in the port. The day had some of the most beautiful clouds and clouds are rare in Crete, unless they follow a winter rainfall. The wind was very strong and the Mediterranean wild so I took a few rolls before my uncovered hands and neck felt like they were melting.
    Then I noticed the spray on the filter so I called it a day.

    It may not necessarily be sailing. It seems to me there is a large contingent on APUG who live on or very near their local coastline and therefore we occasionally get sprayed with salt water.
    It would be interesting to see how many of us are 'coasties' and how many are 'inlanders'.

    My personal preference is to gently soak in a warm soap solution then rinse with warm water and dry with a hairdryer on a 'cool' setting.

    I do the same when cleaning my lens filters.
