How do you remove dried grout from tiles?

The tiles I used Italian porcelain tiles that have many small holes in them. I tried scrubbing the grout on the tiles before drying, but I got to some of late. Today, they are grout in the stands at my tiles. Is their a way to get his case?

If you hesitate to use the acid method, just leave Soak the tiles with water and scrub with a stiff brush. (Circular motion) There is more work, but unless you know what you do, I hesitate acid to recommend to someone who is not a professional. Too much chance of damage to oneself and others.
