I just grouted over my unglazed ceramic tile and the clean up is almost
impossible. I have been at it or 5 hours and only a quarter done. It is
taking a lot of scrubbing and there has to be an easier way! Please
help!!??

You're going to have to use muriatic acid and even that might not work
very well for unglazed tile.

Due to its porosity unglazed tile has to be rinsed and rinsed and
rinsed again with many water changes after grouting, then whatever
haze is left polished off with a dry towel within only a couple hours,
or you're screwed.
