Dirty camera cover

Ben, I guess that it is a constant problem, but is there any way of having the camera weather covers cleaned? One of my favourite cams, Middleton Point is a classic example, at the moment. We have had strong Southerlies down the South coast creating a lot of sea salt spray and no rain, which sometimes cleans the cover.. I look after a few local cameras and am regularly cleaning them, using a soft cloth on a long extension pole. Checking most of the SA premium cams shows a similar blurry picture, so possibly the hosts could clean them? By the way, you're major competitor, Surfline has the same problem!
