Removing dried grout from your mosaic is a difficult and messy process. Having done this a few times I'd recommend spending more time on the grouting process and trying to get it right the first time. There are essentially two reasons why you'll find yourself in this situation, the grout has dried before you've had a chance to clean it off properly or your not happy with the grout colour you've chosen.

While it is a difficult process there are a few things you can do to make it easier:

Wet the grout and keep it moist while you are working.
It takes a few days for grout to reach its full strength, so the sooner you start working to remove the grout the better.
Be careful when trying to get grout off the face of a tile or glass, metal tools can scratch the surface. If you are trying to do this wooden tools can help you avoid irreparable scratching.
A mild acid like vinegar helps remove grout haze.
Metal tools such as a dental pick or grout removal tools (available from hardware stores) can help you remove the grout between the tiles.
Don't let any of the grout end up in your plumbing.

Most of all be patient and work carefully, it may be a difficult process but removing the grout is often better than walking away from your mosaic project.

This article has been written based on the assumption that you are removing conventional grout, i.e. cement based grout. If you are using epoxy grout then what I've recommended may not work.
