Here is the link to get the metal polish and #0000 Steel wool can be found at any good hardware store.
The steel wool gets filled with a black goo as it lifts the dirt out of the metal, change the pad when it starts streaking. Follow up with a clean soft polishing rag. Looks like new. Road tar, dirt, water marks and even skin comes right off.
