Zachary,
If at home, I use a can of compressed air to get the initial grit or abrasive dust from the lens. In the field, I use a camera lens quality blower brush. If there is any heavy film or stain, I then use the Zeiss cleaner with a lens quality cloth. When a lite cleaning is all that is necessary from long storage, then alcohol or water with a lens quality cloth is all that is needed. Over cleaning or too frequent cleanings are not a good thing.
