I need some new information on cleaning the plastic gray rub rail(Hull - deck joint). The rail is resisting my efforts to clean it. In some previous posts Spray "9" was suggested. It does a pretty good job but their are still some persistant dark stains on it that remain. They were black but now they are faded somewhat after cleaning--but are still there. Regular boat soap won't even touch it. I tried Amazon mildew stain remover-no joy. Spray "9" better but still not good enough. The problem is I want to restore the rub rail to like new condition without hurting it. Sometimes cleaning plastic can degrade it if you use a solvent that is too strong. I would not enjoy trying to replace that entire rub rail if it became damaged.Would chlorine bleach hurt this? I know it can have a very bad effect on plastics. How about acetone? Does anyone know precisely what this rub rail is made of? If this were known it might lend itself to proper ways to clean and preserve. I am not happy with myself for letting this go so long. Please advise.
