Mild cleaning agents combined with a coarse-bristled scrub brush often work to clean the brick. Always start in a small hidden area of the wall when testing a new cleaning method to ensure it doesn't damage or discolor the bricks.
Things You Will Need
-
Dust the walls gently with a feather duster or vacuum to remove visible dust and cobwebs. Rags with lint or paper products tend to leave behind more debris on the brick so avoid them when dusting.
-
Mix together equal parts of a dishwashing detergent that cuts grease and plain table salt. Stir the ingredients to create a paste consistency.
-
Rub the cleaning paste onto the brick surface using your hands or a rag. Work in small sections of the wall.
-
Scrub the brick covered in the cleaning paste using a scrub brush that has stiff bristles. Wipe the bricks clean after scrubbing with a rag and warm water. Move onto another section of the brick wall and repeat the process of applying the cleaning paste, scrubbing with a brush and washing off the cleaner.
The Drip Cap
- The bumpy texture of bricks makes them a challenge to clean.
- Abrasive methods of cleaning potentially cause damage to the brick or mortar, especially if the bricks are old.
- Rub the cleaning paste onto the brick surface using your hands or a rag.
