My neighbours wall has turned white so I am interested in finding an answer
From Google ---
The salts that cause efflorescence are soluble in water. Hosing with water will cause the salts to dissolve and be re-absorbed into the brickwork, and then reappear when the brick wall dries out again.
Acid or alkaline treatments are not recommended as they increase the salt content of the wall.
The best method is simply brush off the deposit with a stiff dry bristle brush after the wall has dried out. Then sponge the surface with a damp synthetic chamois or high suction sponge. Use very little water and rinse sponge frequently in fresh water.
