Seems like some kind of oily fog/spray could obscure things until someone took the time to physically clear it. More temporary, but perhaps easier to accomplish?

A very salty spray would be effective. The spray itself would obscure the lens until it is cleaned and cleaning it would be a pain in the ass to do without damaging the lens.

I imagine a sufficiently strong acid could discolor it pretty quickly.
