Can't seem to shine my white sink?!

[scaryt]

Am trying to be a good flybaby but my white sink won't co-operate. It's got black marks all over and bleach won't touch them.

Please help . . . I want a shiny sink too!

He He thats why I didn't even get started with Flybloodylady. I fill sink with hot water and bleach but you say you have tried that what about denture tablets.

what on earth do they put in denture tablets that it can shine my sink . . .

I too have vile white sink which is bane of my life. Hate it.

What works for me is firstly good scrub with Barmans's Friend (like some kind of modern Vim as far as I can tell, and in Sainsburys), then the bleach - small amount left in for a couple of hours/overnight while I bleach the cloths. It still doesn't look perfect, and it's certainly never going to shine, but it does look better...
