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?
Edit: And this pisses me off that I have to think about such things.
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.
Yeah but I am guessing you can’t safely dispense it from a super soaker.
Vinegar might do the trick, and that’d safe in a super soaker. Make it salty for extra impact.
