the best cleaner ever
My 310 is a 1997 and still looks like it is just off the production line. I use "SupperClean from Castral oil", pick it up at your local WalMart. It will clean anything but you have to rinse well or it will eat through anything. mix with water to use on the hull and deck and full for engine and BBQ grill. rinse, rinse, rinse well with water.
