Best cleaner for yellowed smooth fishing gelcoat
My boat has not seen water in a long time, but even when it was taken out every week and cleaned I still had this problem. Well-water from my sprinkler system hits the boat, runs down the deck and into the hatch flanges and water gutters and streaks the bulkhead to a gross off-yellow, I have since fixed the sprinklers. I plan on drilling a couple holes in the hatch flanges so they drain, but need some advice on what to use to clean these areas once and for all so they're easy to stay on top of and keep clean. I also need something good to get all the greasy marks off the smooth finish from working on the boat after a long period of time because magic erasers and chlorox cleanup aren't working.
