Answer 2

Hey I know of a chrome cleaner that is great on metalized plastic grills. It is called Ultra Luster Waterless Car Wash. You just spray it on, wipe and buff. It is so simple and gives you an ultimate shine without the work. It is safe on all surfaces and saves water too. They also have a Metal Polish called Metal Luster that works on the harder to clean areas on all surfaces. Check it out!www.ultraluster.com/goultraluster
