I have already removed plaster, washed the wall down several times and used a wire brush, but still have a white chalky surface when the bricks dry. What can I do to get rid of it?

Try brick/mortar acid. This will work on it. Sometimes even on new bricks they can start to have white faces from the salt being drawn from the brick. A couple of goes with acid should clear it.
