Does it remove stains on a granite sink, I currently use olive oil to moisturise it weekly to remove the brown patches in my black sink,

I do not think it will remove them. I would seal it with our Granite Sealer and then use Polish Preserver to protect it and it from getting stains

Will this product restore the black to a composite black sink and draining board? If not do you have a product that will?

It's a clear product for sealing, Black Diamond is just the brand..
