One question that begs to be answered:
With so many "professionally" used cleaning aids, what would lens and lens filter manufacturers recommend? And would they make cleaning kits for their products? And what would they recommend as a technique to prevent wear and tear of the nanocoatings on the optical surfaces?
We could all use some of the manufacturers' insight, instead of trying an unproven method.
I've always used a rocket blower or microfiber cloth as my first choice, my breath plus microfiber cloth second choice.
Here's your answer lionrock....from the NY times article linked below...
"I spoke to Steve Heiner, the senior technical manager at Nikon
, for advice on lens cleaning"...
" Start by blowing as much dust away as you can with air...the preferred product is a squeeze bulb"
"Friendly fibers. In most cases all you need is a good lens cloth. They are now made of microfiber, but get a good one"
"A perfectly good substitute for light cleaning is “a good huff of breath across the lens,” said Mr. Heiner"http://gadgetwise.blogs.nytimes.com/2011/04/10/how-to-clean-a-lens-the-right-way/?_php=true&_type=blogs&_r=0
