What do you use to clean your lenses?

[Wasatch Rebel]

I need to get something I trust to clean my camera lens. Someone suggested microfiber cloth, but the kind I got is making scratches in my glasses when I clean them (I think that's what's doing it) so I don't dare try them on my camera. Any suggestions for something that works well without possibly damaging the lens?

Bausch & Lomb sight savers. Pre moistened single use so they don't pick up dirt.

Pick up a Rocket Blower or two and keep it handy. I almost never have to touch the lens using this.
I use it to blow off the sensor, too.
