tile mortar removal?

Question

Trying to scrape old Mortar about 20 years old that is kind of hard, and wanted to know if there was a way to soften it up to remove it from a concrete slab, to speed up removal?

Answer 1

Just use a hammer and chisel to chip it off. A quick tap with the tip at the edge of mortar should do it.

Answer 2

wet it, and add some soap this will speed up the soaking of the water,
