A friend with a nice 1957 brick home wants to clean it. He was

I said this might harm his bricks or mortar.

any good ideas?

There are a number of possible ways of cleaning brick Which is best
depends on the condition of the brick mortar and the soil you want to clean
off. Ground walnut shells used in a sand blaster (no sand) is one solution
for example. I would suggest staying away from a high pressure water
washer as there are several ways they can cause problems.
