Hi, I removed the tile in an area about 5 inches by 10 inches next to my tub. I have dry rot about 2 inches in diameter, I have cleaned the area and applied a wood hardiner. I need to get all the odd pieces of grout off the tiles. I know I need to repair the floor but I am ready to tackle cleaning the tiles.

Are you saying you had a rotten floor and patched it with some kind of chemical that hardens? The grout should chip of with a pair of tile nippers and the adhesive will be a bit more difficult. Lots of labor, tell us how you plan to repair the floor. Red Devil Inc 2948 Ceramic Tile Nipper
