Grey indian paving turned orange - How to remove?

[shannahleanne]

Good evening
I recetly had my garden landscaped using Marshalls Kandlar Grey stone.
Its now been two weeks and the flag has turned orange/brown and looks awful. Ive tried scrubbing the area, rinsed with fairy liquid and nothing is removing the marks.

I have photos but not sure how to share?

If you upload photos it would be useful, you need to check with the installer that they have not used any cleaner (acid on the stone) as this can extract the iron oxide out of Kandla Grey as it is a very ferrous material. Also that they have not laid it on building sand. If not then you possibly need to go back to the supplier. We've supplied stacks of Kandala Grey over the years and almost every time we have had a similar complaint the builder/landscaper had used acid to clean the paving.

this is unusual as kandla grey is normally bullet proof
pics will help

Would agree with KeburDave - we often see this as a result of acid cleaner used to remove the excess mortar left to dry on the surface of the slabs. Without even seeing the photos, I would be drawing the very same conclusion.
