Acid stains on my newly layed kandla gray Indian stone

[conzyv123]

Was told by the building supplies shop that the patio cleaner would be fine on my new front garden, even after I said I'm sure acid based can't be used on Indian stone, but was told no they use it all the time, luckily I only used on the ending blocks but it has ran into the paving and I have lots of yellow patches, is there anything I can do to help with this issue ? 🤞🤞🤞🤞

You will probably have to just let it weather Your not alone Suppliers advise is often quoted on here 

They only sell the stuff

that is the downside of cheap indian sandstone, its a bugger to keep clean and look fresh.

It's from https://ammaaristones.co.uk/, it's been down less than a week, the stains are from hydraclauric acid.

For anyone who is wondering I have used LTP Forrex diluted 1/3 and it's has removed the stains within 2 hrs 👍👍👍🎉🎉🎉🎉
