Acid stains on my new kandla grey Indian stone "HELP"

[conzyv123]

I recently laid kandla grey Indian stone in my front garden and used acid based cleaner in the edging stones for the excess mortar, I was instructed by the staff at the building place that it was the right stuff to use as I had read that acid base may not be suitable but they assured me it would be fine, it faded the edging blocks, which I can accept but where it's dripped on to the Indian stone it has rusted it, is there anything I can do? It's been down less than a week.

This probably isn't much help to you, but had you not said that it was unintentional, I would have assumed that the flags were naturally orange/grey. I guess if only the ones near the edge are like that then it's more obviously a problem.

Pretty neat job BTW, as a DIYer I would be happy to have achieved that.

I'm inclined to agree with the above. Perhaps it looks worse than the pics show and no doubt you're biased but really it looks OK. Tidy job too as mentioned.

Thankyou, appreciate the comments, but yes in person it looks very yellow have ordered some LTP non caustic rust remover for stone, apparently works well so fingers crossed

For anyone wondering I have used LTP Forrex diluted 1/3 and it has lifted the stains within 2 hrs
