Black limestone - Help

[JP1980]

Hi guy's
I have had black limestone put down in the back and the joke of a builder has used brick acid to try and tidy the mortar stains.
After doing a bit of research on this it seems I am going to regret choosing it.
I understand it should of been sealed before it was put down,I have looked a product up called dry-treat which seems to look o.k, but what would I clean it with before i seal it.
Can someone please recommend a good cleaner and sealer.

From what we spoke about on the phone, this is all very do-able.
