The previous owner of the house my daughter has bought had at some time mixed concrete and or mortar on the patio slabs. I have used a brick and patio cleaner to try and remove the stains. This unfortunately has made it worse.
I have read your excellent FAQ "Fixing acid stains" and was wondering could you please tell me what type of slabs these are and what you think I could do to try and get them to somewhere near their original colour, or even a uniformity of any colour.
Thanks.
