Many years ago, in an attempt to keep the cost down for the customers, and before I gave up being so stubborn, I did many experiments with such parts, including Protek, naphtha cleaning, perchlorethelene (with and without ultrasound), and repinning with all of the above; even rebushing. It always returned, because the root problem wasn't removed, and the more that was spent on a temporary solution was that much more taken from the real fix. Further, Protek will make a difference, but the difference can last as little as a few days in some actions. Bob Davis
