Mix up cleaning solution for stained grout

Q. I neglected to clean the black grout from white tiles quickly enough during installation. My new floor is stained, and the only remedy so far is to sit and hand scrub ­every single tile with Barkeep’s Friend and a plastic scrubber pad. After hours of this I was ready for the chiropractor and stopped. What can I do to remove the rest of it? Have I damaged the glaze on the tile beyond redemption?
