I have been using Eagle One Aluminum Wash & Cleaner on the 5 spoke. Seems to
work great especially on Audi brake dust. As for leather, use something with
sun block especially if you have the convertible. I've used Turtle and
Amour-all products. Both are OK.
For leather, I use Lexol Leather Cleaner and Lexol Leather Conditioner
(available at Pep Boys or at many online places like www.carcareonline.com
for example). For alloys, I just use the same car shampoo that I use for
the rest of the car - Meguiar's Gold Class, available at Target. The key is
to wash the rims frequently to not allow brake dust to build up, and never
wash them when they're hot.
Same reason why you should not wash your car in direct sunlight. When the
surface is hot and you suddently treat it with cold/cool water, the drastic
temperature difference and rapid cooling is not good for the finish. It's
even worse with rims because when you drive, they become very hot from the
nearby brakes, especially in the front. That's why it's a good idea to let
them cool off for 30 minutes or so before washing.
No, not necessarily. The idea is just to keep the the temperature
difference between the alloys and the water down to a minimum, if possible.
If it's 40 degrees C outside and you just finished driving with heavy brake
use, don't pour freezing-cold water on them. If it's 0 degrees C outside
and the car sat outside overnight, don't pour steaming-hot water on the
Hope this helps.
