First, blow off any major dust with a air bubble. I use Kodak cleaner with micro fibre cloth (Rodenstock cloth is ok, but I don't really like it, I use other cloth...which my sister got for me free from UK), clean the lens in circular from center out. After cleaning, give a breath to it...then clean it off again. Blow with air bubble...done.
One thing I learn after cleaning my lenses is...NEVER CLEAN YOUR LENS! No matter how careful or skillful you are, your lens will never look like the new one again. There will still be some sign from cleaning at the corner of the element. Just blow your lens with a air bubble.
My 2 cents...
