sulfmaic acid, it comes in crystal form in a small platic tub. You can get at home depot in the tile department, Works great just read the instructions.

If it is REAL TERACOTA you should first try to scrub the imperfections before you use any acid on it. If the tiles were in fact sealed before grouting the cement grout (it is cement grout I hope) should scrub away using warm vinegar water and a power floor scrubber.
