How to get grout out of "shattered look" chevron white tile?
I installed some white chevron tile for bar walls in my house and the tile is the shattered look. I have tiled many walls/floors before but had never used the shattered look until my wife wanted it behind the bar. I picked up 7 boxes at Lowes and after I grouted it I noticed that the grout actually seeped into the teeny tiny cracks on the surface of the tiles making them look dirty. For some reason there were variations in the boxes I bought and it only sunk in the most on certain boxes of tile. In the pictures I attached you can clearly see the difference where the grout is stuck in the small cracks within the "shattered look" of the tile. My question is....How can I get the grout out of these small cracks? Last resort I will have to cut out the bad areas of tile and redo the drywall and lay new tile again. I was supposed to seal the tile before grouting so this didn't happen but I didn't read any sort of instructions before getting to work. I have tried a metal brush on the end of a drill to try and get it out, all sorts of under the sink products. I have run out of ideas! Any insight/help would be greatly appreciated. Thanks!
