I descaled my sink but now its ruined!

[kid]

I used a descaler to get rid of the limescale around the taps and edge of my stainless steel sink.

Well it got rid of the limescale and in its place is a rather ugly faded mark. Instead of being stainless steel, its now gone dark where the descaler was. Is there anyway I can restore it back to the original colour or at least closer to it.

I have even considered pouring more descaler over the bits that weren't affected so it all looks the same colour! But that will be a last resort.

Am I right in assuming there is no cure then!
