I purchased an A4 1.8T a couple of months ago (my first Audi) and I'm really enjoying it. The only problem I'm having is the brake dust on the front wheels. I tried wiping down the wheels with a wet paper towel every day and that keeps the wheels clean, but am I scratching the wheels? If I shouldn't do this, is there something else I can do to help keep the wheels clean? Thanks -- Rodney Henderson
