Anyone have an easy solution for removing old grout (8 years) from tile

My first grouting came two months ago when I repaired some countertop
tile in our rental. The grout I used was Portland cement and colored
sand. Don't know about yours.

Any acid will react with cement and dissolve it. So, try vinegar and
sponge it on a bit of the unwanted grout.
