People also ask, will vinegar clean mortar off bricks?
Vinegar can be used to clean indoor or outdoor brick. It's especially effective on efflorescence, the chalky white salt crystals that build up on the mortar. Mix 1 part white vinegar to 5 parts water and use it to remove the efflorescence with a scrub brush.
There are other acids that will react and dissolve the alkaline chemicals in the mortar. Even the white vinegar found in your kitchen will work to some degree. The challenge for you is to find an acid somewhere between vinegar and hydrochloric acid that will efficiently remove the mortar buildup.
