So after trying every product Bennington and Semtex recommended to clean my ice white interior and failing miserably. I had given up hope of ever getting my boat clean. I ended up grabbing a bottle of korkays rv/ black streak remover that I use on my camper. Tried it out on a seat that’s getting replaced anyways from a defect. Omg the difference it made. I never knew my seats were suppose to be this white. I’ll try and upload pics after it dries more. It’s hard to capture it with my terrible iPhone camera.
