we all make mistakes! im guessing you've got some nice pinkish stains or similar on the slabs? as far as im aware the answer is in the last line of your question!
Unfortunately I think you are going to need to relay. Im not sure there is any other option.

How about the black powder colourant for adding to pointing mixes - light overwash with a dilution of water: powder ? Never tried it...but might be worth a go before re-laying..?
Stain the whole lot black with some stain.. (i spilt some on my concrete path and seems to have permanently stained it black)

I decided to put myself if the clients shoes and I took the bull by the horns and Wednesday we took up about half the Limestone (badly stained white acid marks) and relayed new. It was a tuff day on the breaker but with all three of us on the job we had 15m2 of fresh laid by home time.
I'm heading over this morning to point up, - and get paid! Clients have been very understanding and appreciate my honesty and dealing with the issue,
A valuable lesson learnt - Wickes patio cleaner and Black Limestone No No!
Very honourable Mark.
Not the best result for you, I.m sure but excellent client relations exercise and learning curve.
Well done:)
