placo1,
Below is a web address of a Benz fan who uses "No Touch" tire cleaner. He goes into detail about the unique properties that make No Touch the best. This is the product I use as well, with good results. The dusting is not an issue like you'll find with Armor All. Everyone I've turned on to it for detailing, now uses it. But everyone has their favorite products, this is the easiest I've found.
Regards,
