Just tried Ethos Iron Decon v2 wheel cleaner. Did a good job cleaning my wheels before I graphene coated them. Cleaned the barrels so well that I was able to see the witness marks from the grease pens they use at the factory. Smells pretty good too. But hopefully with the graphene coating and new Powerstop Z26 pads, I'll have less dust and only need to use the soap and water in the bucket while washing the rest of the car.
