Tried the angle grinder with a wire brush but it was too fast and ' blued ' the bricks.
A mains powered drill with a nylon flapwheel did the job but I needed to go over the worst areas with a hand wire brush first.
Flapwheel also good for the mortar joints. I guess the salt hadn't got too solidified yet as it came off like talcum powder.

I went over all the bricks afterwards with a cloth and the wood dye to colour any residual white in cracks, etc.
I wonder if the severe cold has had something to do with the problem as this is the first year we've had it happen. I'll keep an eye on it from now on and see if it comes back.
I'll post a pic of the ' after ' in a minute.
