How can you remove moss from bricks without harming the bricks?

A good way is to pressure wash the bricks. This will remove the moss and clean the bricks at the same time. It's good that you pressure wash your fences and outdoor walls regularly.

Use a roundup to kill the moss, after it is dead pressure wash it off.

use a hammer and chisel around the cement grout lines of the bricks you want to remove

first place your tongue on the sap. then carefully lick it off without missing any spots. after this you can either spit it out or swallow it. i tend to save it in a cup as my famous secret recipe

If it won't come off with a pressure washer or paint stripper, you may need to have it sand blasted. Be careful sandblasting soft brick because it will eat it up.
