That's pretty much my routine, too, except before I use the microfiber cloth, I try a very soft brush on stubborn particles that won't blow off. Then, if all else fails, I use Kodak Lens Cleaning solution and Kodak lintless tissues. As someone said, apply the solution to the tissue, not the lens surface. One drop will usually be plenty. I start in the center and work my way to the edges, then dry it with clean tissues using the same pattern.
