Before you touch the brick with any cleaning liquid or tool, take time to shield everything nearby. Acidic solutions and even aggressive scrubbing can harm adjacent surfaces like wood flooring, baseboards, metal fixtures, and delicate plants outdoors. Lay down heavy-duty plastic sheeting or drop cloths directly beneath the work zone, and secure them with painter's tape so they do not shift while you move around.

If you are working indoors, ensure the space is well-ventilated by opening nearby windows and setting up a box fan to pull air outside. Put on rubber gloves, eye protection, and old clothing that you do not mind ruining. Mortar and grout residue can be harsh on skin, and splashes are almost inevitable when scrubbing rough masonry surfaces. Taking these preventative steps ensures that your cleanup remains focused solely on the brick rather than collateral damage to your home.

Mix the Cleaning Solution

You do not need harsh commercial chemicals to break down cementitious haze. A standard mixture of warm water and household white vinegar works exceptionally well for most indoor brick installations, as vinegar contains mild acetic acid that dissolves calcium carbonate without releasing toxic fumes. Fill a clean bucket with warm water and add the vinegar, using a ratio of roughly three parts water to one part vinegar.

If you are dealing with stubborn haze outdoors or on particularly resilient brick, you can substitute the vinegar for a specialized masonry cleaner, but always dilute it according to the instructions on the container. Never mix different chemical cleaners together, especially bleach and acids, as this creates hazardous gases.

Apply the Liquid

Dip a large, soft-bristled sponge or a clean rag directly into your bucket of cleaning solution. Squeeze out the excess liquid so that the sponge is damp and heavy, but not dripping uncontrollably. Gently wipe the solution across a manageable section of the brick surface, roughly two feet by two feet at a time. Do not soak the entire wall all at once, because you want the solution to remain wet on the surface long enough to penetrate the haze without drying out prematurely.

Allow the liquid to sit on the brick for a few minutes. You may notice a slight fizzing or bubbling reaction as the acid begins to break down the cement film resting on the face of the masonry. Keep a close eye on the mortar joints during this waiting period. The goal is to remove the haze sitting on the brick face without softening the fresh mortar holding the bricks together.

Pay close attention to the textured indentations and pits in the brick face where haze loves to hide.

Inspect and Repeat

Step back from the wall and let the brick dry completely.
