Tor is you have lots of it would strongly suggest to have it professionally cleaned !!!
Depending on body and lenses it would depend. On Pro camera and L (Canon) lenses there is a good seal and more protection. On my after being on the beach doing shorebirds I use a damp cloth and go over the cameral/lens If you need can use a small toothbrush for small hard to get places !!!
Either way would get the salt off as soon *** possible btw on place I find neglected on lots of cameras is around the viewfinder and if you look close will see corrosion !!!
Hi, have you ever tried soft cloth, giottos blower and lenspen to clean your lens? it's good from my experience, use blower to blow away the dust (salt easy to drop), then brush with lenspen, at last wipe with soft cloth. hope it helps! :)
