Hi,
I laid about 200 square feet of stone in my foyer. I grouted the stone yesterday and when I finished, the grout where I started was too dry to wipe off with water and a sponge. Also, I tried vinegar, didn't phase it. There is a substantial amount of grout on the tops of the stone, not just a haze. My drill and a wire wheel brush work, but it's very time consuming.
Is there a better way to remove this extra grout? There's nothing special about the surface of the stone. It's rough. It can take a little etching or scratching and I'm not worried about it.
Thanks, Jo Jo
