This past weekend I was in a large parking lot breaking in the Force .28 engine in my new Jammin X1 RTR. I accidently ran off the parking lot and into a water puddle (I turned a split second to check on my little boy playing off to the side). I immediately cleaned the car and sprayed it down with WD-40. I accidently got some on the brakes. What is the best way to clean off the disc brakes and pads?

Thanks.
