Just remember that photo lens cleaning tissues (like the Zeiss) are best, in part, because they are designed not to affect the lens coating.
I still prefer a micro-fiber cloth and my breath - if the blower or brush fails.
On the other hand, maybe someone knows the chemical contents of the average person's breath and knows a reason it shouldn't be used? Is it affected by garlic and onions?
My daughter in law is Japanese, she taught me the virtues of microfiber cloths, them suckers clean anything and tough spots just wet them with water.... amazing.
