best grout cleaner ?

Finished laying my porcelain tiles and grouted.
Have some discoloration from drying in grout lines. For the most part
this cleans up with scrubbing. Any cleaners recomended ?

It sounds like you have grout haze. Use some white vinegar and a stiff bristled nylon brush to scrub the grout and it should come right off. The vinegar acts as a mild acidic solution to remove the haze.
