What are some ways that you can clean the brick work on your house and make it look newer, without harming the brickwork in any way?

I live in a very, very old house. Well over 150 years old. Its a house of brick on a stone foundation. I have heard that sandblasting of bricks is very bad as it widens tiny cracks.

I have heard that sandblasting of bricks is very bad as it widens tiny cracks. It makes the bricks look brand new but its bad.

I wonder about pressure washing too, though that could be a good alternative.

Over the century and a half the bricks on my house are marked up here and there, excess paint drops, and whatever else.

I'd like to clean them up but I'd like to be very careful as well.
