Rinse with fresh water first to get off the grit, salt etc. Then a soft sponge with lotsa soap, boat soap or wash and wax, then polish with 210 of serious shine spray. You have to be carefull using products not made for this application, while it may look good for a while, it can degrade the plastic. Rain-x, windex and anything with ammonia is a huge no-no. I've not seen any long term reports of pledge type products but the products I've recommended are products both Whaler and Sea-Ray recommend on the glass and the 5 year old isinglass on our Sea Ray bridge still looks great.
