I used a chemical based paint stripper to remove all the old paint and grime from the caliper. Then I took a bristle brush attached to a motor to remove all the softened old paint. After that I used paint thinner to clean the caliper of the paint striper. Next I rinsed them in water. Then I took a hair dryer to make sure they were completely dry. Give them 3-4 coats of paint in accordance of the directions on the can. And I would recommend a clear coat over them to help you clean them later.
