It's basically the same as using a tooth brush to clean every little crevice of the bricks, and it removes every last speck of dirt, fingerprints, dust and smells from the parts without even using soap. And since it's mechanically cleaning the parts, you also get rid of stuff that soap doesn't dissolve well, such as that thick coating of dust that can often accumulate along the recessed edge of Technic pin holes. You'd be amazed at how much muck, dust and dirt falls off even supposedly clean parts.
