The Best Ways to Clean Exterior Brick

Brick homes generally do not show dirt easily and therefore need little cleaning. In the event a brick home does become dingy or show signs of mold, you can usually clean it easily and inexpensively.

Brick is easy to clean and maintain.


Most of the time you need only rinse down the brick on your home with an ordinary garden hose. You can use a spray attachment if you would like to target a specific area. Stand 4 to 5 feet away from the house and spray the surface from side to side in a sweeping motion, beginning at the top.

Scrub Brush

Clean mold from exterior brick by first spraying with a garden hose. Mix a solution of 1 cup bleach to 1 gallon of hot water. Put on rubber gloves and scrub the moldy area with a scrub brush. Rinse with cool water from the garden hose, then allow to dry.


Use a power washer sparingly on exterior brick, as it can loosen mortar and cause damage to the structure. If you need to remove dirt or stains in a particular area, and a regular hose isn't doing the job, target only that section with the power washer. Set it to the lowest pressure setting necessary to clean the area and avoid causing damage.
