Does not "DISSOLVE" MORTAR OR GROUT
does not work as advertised.  it will help in softening the top of the ceramic tile mortar/grout, but will not fully dissolve mortar even after repeated sprayings.  I ended up using a 4.5 inch double row grinding disc on my grinder to remove the mortar for the 12 tiles that i was replacing.  used the remaining spray to keep dust down when using the grinder to remove the mortar.
