Get yourself a spray can of IPA. No, not the light ale, but IsoPropyl Alcohol.

It's the stuff the opticians use to clean your specs after they've handled them.

It will evaporate quickly so gently wipe the glass with a tissue and just wait a few seconds. Because it is such a thin film it makes it look initially like you've wiped part of the coating off the lens; hopefully you haven't.
