Will this sort out water marks as well. Because some idiot left the passenger side window open a tiny bit so ive got this brown outline of where the water reached. There is also a suspicois white mark on the back seat which looks like sex wee but isnt. As the girlfriend is back from uni soon I dont want her thinking ive been naughty while shes been there. Before people ask no I havent and it is yougat that a friend spilt.
