I remember watching a guy that makes optics (he's on you tube)...
If I remember correctly, he uses a sprayer to shoot dirt off.. search him out on you tube.

I'd highly recommend wearing particle-free Nitrile gloves when handling the optic. That goes for cleaning AND using it. Skin is a great particle source.
