Before cleaning with fluid and tissue, blow any loose particles 
off the lens with a blower bulb or compressed air. Then apply 
some cleaning fluid to a tissue, never directly on the optics. 
Wipe the lens gently in a circular motion, then remove any 
excess  fluid  with  a  fresh  lens  tissue.  Oily  fingerprints  and 
smudges may be removed using this method. Use caution; 
rubbing too hard may scratch the lens. On larger lenses, clean 
only a small area at a time, using a fresh lens tissue on each 
area. Never reuse tissues.
