How clean grout from a brick ?

I would like to know as well. Has anyone used fake bricks that are real bricks but only about half the thickness?

When your adding the grout you should have a bucket of water and a sponge softly cleaning away excess grout. This will prevent the grout from sticking to the brick.

If it already dry... I'm not sure. :(

You can clean the grout off the brick or tile with Limeaway.

Had the same problem when I did my chimney.. but I painted over the brick.. so you can't really tell much.. good luck.

You are using a bag to apply the grout already. That's GOOD. Use a dowel, pencil, round handle, to smooth out the grout in the grooves. This is called "striking". As it starts to dry use a stiff brush to remove any that squeezes out and off the brick. It should flake right off. Try not to brush the grout lines. If there is any haze use a damp cloth or sponge to remove it. Cover the countertop to protect it.

I have just used the brand-name Limeaway.

Another thing, you could try putting the grout in a plastic storage bag and cutting a small part of a corner of the bag and pipe the grout into the space (like piping icing onto a cookie), thus getting less grout on the face of the bricks.

The logic behind the Limeaway is I figured grout contains lime so it stands to reason that a product that is designed to remove lime might work, and I was right.

This is how I do it: How to Clean Grout

1. Remove surface dirt with hot water and a towel.
2. Mix together ½ cup baking soda, ¼ cup hydrogen peroxide, 1 tsp dish soap.
3. Spoon cleaning agents onto grout and let sit for 5-10 minutes.
4. Scrub the grout lines with a brush. ...
5. Wipe clean.

Fill a spray bottle with half vinegar and half water. Spray the tile and allow the solution to sit for a couple of minutes before wiping it away with a clean cloth.If dried grout reside does harden onto the tile, you can try to remove it using vinegar, a chisel, or a diluted sulfamic acid solution.
