I would like some advice on removing small stains on fairly recently laid unsealed indian stone, possibly caused by professional controlled release lawn fertiliser. To my knowledge the fertiliser didn't contain iron, although I am wondering if that information is accurate. The actual fertiliser supplier is telling me it could be the salt in the fertiliser granules that's ereoded the stone, however a supplier of indian stone tells me it wouldn't erode.
So the actual cause is a grey area which is making it difficult for me to decide on how to proceed. I've tried the hosepipe without success so I'm now hoping if you can advise on pressure washing or chemical treatments please.
I'm having trouble trying to upload an image to this forum. Any ideas?

OP,
Can you post a photo of how bad the staining is, as we have had to clean up loads of this type of staining after "lawns people" have messed peoples patios up.
