People worry about the dust and the fingers that leave greasy marks on the lens,but i have to worry not only for those,but also for sloppy kisses from Avra(my boxer girl) :) .Twice she slobbered(spell?) the brand-new 70-200 lens.
I use the cleaning paper of kodak and i wonder what do you use?just paper,cloths or a special liquid?

I use a paper and a cleaning fluid "optic" from Hama :)
If it is just dust, I have a little brush with air, and a air spray.
