  1. Thank you so much this information was certainly helpful. The white vinyl seats on our boat have yellowing darker from the sun. Any recommendations?
    Again thanks

  2. We sprayed this mildew remover Star Brite stuff on the giant clusters of mildew stains (they were rampant, apparently our camper was put away wet without opening to air once upon a time) and the dark spots became black. When we turned to treat another area we would turn back to where we had sprayed and the black spots became a light brown. I swear it was so amazing we just stopped and stared and the light brown spots faded into gleaming white.
