It is always important to keep bricks as clean as possible while laying and tooling. If mortar has been allowed to dry on the surface of the bricks, the options you have to clean it off are as follows. Each process should be tested first and should ensure the facing bricks are not damaged:

a. Dry brushing

b. Wet brushing

c. Using a ‘like coloured’ brick to rub the stained brick

d. Pressure washing should only be used as a last resort as it will damage the surface and the mortar joint if not completed correctly (this method cannot be attempted until the area has been allowed to set for a minimum of 7 days).

Acid cleaning should be avoided.
