The Michelin Brake Dust Repellent is simply a foamy spray that is wipe on wipe off I always forget to spray inside the barrell of the wheel with the Michelin...
Haven't looked a the ingredients but I keep a roll of autoshop paper towels (blue) in the trunk and the with a little detailing spray the brake dust wipes right off. A quick wipe of the wheels and quick application of 1Z on the tires always makes the car look like it just came back from the wash. I stopped quick detailing the paint to avoid micro marring unless it to clean off bird droppings.
btw, Klasse VLRP on interior plastic (door sills, center console, rubber seals, etc)My favorite detailing product
