Cheers folks. For future reference. Nail polish, degreaser etc is a no no. But it faded the stains to a lighter brown which is better on yellow than black. D-Rings! Yacht chandlers (Which is posh for a sailing shop. Got to love London. Anything you want is somewhere local) Only £2 for two. And they are hefty muthas. So just the cinch clip left. I can feel a begging email to Seattle coming on.
