It does at least help with filter cleaning, as water can be wiped away quite easily.

There are two kinds of polarizing filter available to photographers—linear and circular— with the latter design most suited for digital photography.With circular polarizing filters, the amount of enhancement is adjustable. When the front plate of the filter is rotated, the angle of polarization changes and with it so does the amount of polarized light that passes through the filter. This allows for precise control over the degree of polarized light that is to be removed from any given scene. A polarizing filters ability to add a “pop” to almost any kind of image taken out in the natural world is the reason why I never go on a photography trip without at least one of these filters for each of my lenses.
