Really? Steve, if I was you I would move to Melbourne, no people with sand damaged skin here.
I have been in Perth many many times, in fact I lived there at one stage for two months and I cannot recall ever having been sandblasted.
So you must replace your protection UVs every two weeks or so because if this is factual what you are saying the must be pretty well opaque by then every time. (I don't think so)
No offense, but I think you are massively exaggerating.

Always use the lens hood, it provides pretty good protection. If you see just "surface dust" on the lens, use the brush of a lens pen. (Lens pens are pretty good and safe) And here is a trick I have learned from an old pro; If what sticks on your lens appears to be more than just dust (perhaps a grain of sand ?) roll up a small piece of bread into a ball and gently press down on the offending matter and carefully lift it off without sideways movement. But I must be honest, I can not remember when last I had sand, or anything else that sticks so much on the lens, that I had to use this method. After that polish the lens with the carbon side of the lens pen. Trust me you won't have a problem.
(When using bread make sure it is free of salami or cheese!)
Just kidding !

Hi
You beat me to it, I was going to suggest Marumi polarizers also. I have one for every lens size (5 in total). Used some Tiffen filters in the past (they are good) but I think Marumi are better.
Polarizing filters test - Marumi DHG Super Circular P.L.D 72 mm - Lenstip.com
Also, as to UV filters, I think they have no place for digital cameras any more. They are pushed hard by camera sales staff as an extra profit item after the camera sale is made. A big deal is made by them to convince unsuspecting customers of the benefit of lens protection. (After all lens protection can't be bad, can it.)
I have used cameras for 40 years and in the film days I certainly used UV filters (and they were needed) and I have NEVER scratched any of these filters, so why should I suddenly start using them on my DSLR ? If I have never scratched any filter so why then should I suddenly scratch lenses. Check any one who has used UVs on their lenses and see how many UVs are buggered.
When walking along the beach just put the lens cover on. Its not that you are constantly bombarded with sand like inside a sandblaster, wait for the right moment, take the lens cover off, take your shot and put it back on immediately after. That easy.
Any extra glass (no matter what the quality) added to the lens which the lens maker has not intended as part of the design is an extra piece of matter that can introduce reflections and through which light has to pass with unforeseen consequences.
Above opinion is based on personal experiences and not hearsay.
