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.
Someone who isn’t me is wondering if there is any sort of rapid glass etching compound that would help to decorate the lenses for them.

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.
