Looking for some advice for cleaning mortar off back off slabs.
I've been offered some slabs that have been carefully lifted from a neighbours back yard. Slabs are in great, near new condition. They were laid but never got pointed but when they laid them they used spot bedding method and there are spots of mortar on the back of slabs.
What's the easiest way to remove these spots without breaking or chipping slabs.
They are giving me the slabs for nothing so if it takes a while to clean it off its fine.
Appreciate any advice.
