Spent HOURS cleaning my '90 Gulfstream with bleach and water and a product called Grease Lightning which worked very well. I also used Magic Erasers. Everything came out perfect and bleach white. I did the whole cockpit area including floor, baitwells, livewell , fishwell etc.... Well, that was 4 days ago when i finished and i just hopped in the boat( its in my yard at my new house) and there were stains ALL over everything in the cockpit from little red berry things that dropped over the past two days from a Red Maple tree that is above the boat. I tested one area with grease lightning and a magic eraser and they did NOT work at ALL. I think the berrys dropped and stained the area and then dried onto the surfaces. Does anyone have any suggestions on how to remove these stains??
