I would recommend a carbon-fiber brush like the Audioquest brush for removing loose dust.
For dirt that this won't remove, I recommend the GEM Dandy, which uses high-pressure water to clean records. You might even be able to make a device like this yourself if you're handy; it's made of standard PVC parts. I now prefer this to my Nitty Gritty 1.5.
