I'm sold, Harley Davidson Wheel Cleaner...

Upto now I've been using the MqGuires 'Hot Wheels' product. I felt my liver getting heavier from the toxity of that crap. The Harley Davidson stuff is almost lemony in smell and does a terrific job on getting the brake dust off. Drop by your local Harley dealership and grab a bottle. The price is comperable.

Next up is the Harley leather treatment. That makes your interior smell like a sweet mommas slice after 500 miles of wild drinking and Harley riding!
