Sanding residue on brickwork

[Paintbrush]

Yup, yet another question from me

I have sanded down the porch and other areas mostly using wet and dry.

Some of the dust has run down the brickwork when wet, I didn't pay much attention until now when I hosed off the areas to find the brickwork marked with a white powder wash.

I have scrubbed the area using detergent and lots of elbow grease, is there another simple way?

It's not paint only the dust from sanding?

Bricks are yellow, similar to page 32 on this pdf (this takes a while to load)

..again.

Do you have a pressure washer, that should shift it, just dont hold the jet to close to the brickwork.

I do, but nervous of using it ever since it lifted the stones out of the tarmac drive

I'll give it a go as you suggest at a distance.

Cheers,

On the proviso that your pointing is sound you should not encounter any problems.
