Thanks freddo and El Buho.

Unfortunately freddo that was the method I had previously used. The acid seems to be stubbornly burnt into the grain in the sink.

If you have a Woodburner try using the ash from the fire
Have you tried filling it with hot water and putting in a large dose of Domestos which you can get from Consum,leave it for a couple of hours then drain and wash it out , works for me

Carl, If its that bad it might be worth buying a new sink
They are not expensive , i changed mine a few years back when i replaced the mixer tap and i am not a plumber, just found sealing it a bit tricky
There is a a good selection at leroy merlin, but any hardware store will stock them
Also i bought a spray a few years back from a place in quesada that stocks household goods , cannot remember the name, but it was like astonish and for stainless steel, it worked a treat without any elbow grease
