I've installed a limestone patio on a compacted sub base with 40-50mm full mortar base. Happy with how the laying turned out but think I have messed up by not cleaning the slabs fully when laying. I have all these stain marks on the slabs. I have tried floorseal patio cleaner.
Is there any recommendations for removing these stains?
