I want to get advice from our members on how to clean PCCBs without causing any damage. I routinely would use Meguiar's acid based wheel cleaner but that is not possible with these brakes. I have seen recommendations for simply using detergent soap like tide but that is not going to budge road tar. Other recommendations included P21S wheel cleaning gel but some say although it's safe it's not all that effective. If anyone has first hand experience with PCCBs and have a tried and true method for cleaning them that works please post.
