Virosol good. (use it neat) but pre-wet first.
Screwfix No Nonsense Degreaser good.
Hypo is the best. Don't get it on your skin or your clothes...or anything other than what you are cleaning.
Tiger stripes, magic eraser pad with some 'Pink Stuff' (tub) on. You won't get rid of them but you can reduce them visually.
If you have a Gardiners Quik Loq adapter, you can use 2 elastic bands to hold the magic eraser in place. Cut the magic eraser 1 inch bigger all round than the small surface of the the QL adapter.
