Take a FULLY wet towel an let it sit over night. Make sure it is wet enough that the towel will still be wet by morning. You should be able to scrub the excess grout off with a scotch bright pad at that point.

You may have to use a flat edged screw driver or a spoon to scrap it off. It won't damage the tile and you should get a clean edge that way.

Thanks. I tried a little vineger and it works too. I think I will stick w/ the less hazardous one for now.

There is an acid that works. I would go to a tilestore or a big box store and ask them the name of the acid to remove grout from tiles. Be careful using any acid product.
