How Do I Clean a Camera Lens ?

i was in canda in niargra fall maid of the mist and got water on it my camera still works

Get a lens cleaning kit. It will have lint-free tissues and the correct fluid. Or you could get a soft cloth that's safe for coated optics, then just breathe onto your lens, enough to leave a film of light mist, then wipe in a circular motion with the soft cloth.

Don't use regular tissues or toilet paper. Also, don't use your shirttail, unless you want to put scratches on your valuable lens.

Use lens tissue or glasses cloth that you get from an eye doctor. If that doesnt remove that residue use lens cleaner from a local camera store.

Well Terisu may well be correct; however I would put no fluid on the lens....just lens tissue.
