What is the best mortar remover?

This question was asked by

I am in need of a non acid based mortar remover to apply to a newly laid black/blue limestone patio, is the Green klean industrial remover suitable??

If you are worried about damaging the stone I would probably suggest using the Ecoacid rather than the Green Klean, it will do the same job but it is not as aggressive as the Green Klean. (link below)
