Cleaning cement from brickwork?

Nearly finished building my brick BBQ. How can I clean the cement off the brickwork and bring out the natural look of the bricks. Friend at work told me there is something I can paint on, leave for a few minutes, then hose off. But he can't remember what it is. Anyone help. TIA

Now if you had only taken the advice to use lime mortar instead of cement... And when you get a bit better at bricklaying you won't get any mortar on the brick faces. But for now you'll have to get some brick cleaner. Ask at your local builders' merchant. It comes in various forms but is based on hydrchloric acid. It disolves cement (and a few other things so take care).

Brick acid. 30% HCl.

Scrub it in with a wire brush if the bricks are hard, or a scrubbing brush if they are not.
