Removing limesale from a concrete kitchen top

[Yukster]

My London water is alkaline and limesale sediments have accumulated on my concrete kitchen top. How can I remove it without damaging the concrete? The pic shows the worst affected area.

Resin worktops go white like that with solvent..
I accidentally put a paint brush down on a resin worktop that I just cleaned with white spirit and it went white.

You think that's marble or other? You can tell as stone is cold to the touch.

If that is lime then try a lime scale remover but I'm not sure it is?

The worktop is made of concrete. The white marking on the worktop is limescale.

Unfortunately, applying any acid to the concrete will leave a permanent stain. This is one of the downsides of a concrete worktop.
