I use a rocket blower to get off dust, then a LensPen for smudges or any gunk that gets on them. (will use the LensPen brush that's attached if I'm away from home, since I don't bring the rocket blower out and about.) Been using the Lens Pens for about 6-7 years now and I absolutely wouldn't be without one in my bag. They clean the lens perfectly, no scratches and it takes up almost no space in my bag.
