Can You Pressure Wash Brick Veneer?

Cleaning the exterior of your house is an essential part of home maintenance, and when it comes to brick veneer, it’s important to exercise caution and adhere to the appropriate pressure washing techniques. Brick veneer, although durable, can be susceptible to damage if not handled properly during the cleaning process. With a recommended pressure range of 500 to 1000 PSI for masonry cleaning, it’s crucial to use low pressure to prevent any potential harm. Professionals often opt for pressure levels between 100 and 1500 PSI to ensure a thorough cleanse without compromising the integrity of the brick. It’s worth emphasizing that individuals without sufficient experience should refrain from exceeding 2000 PSI, as this can pose significant risks.

Is It OK to Pressure Wash Brick?

Excessive pressure can cause spalling or damage to the surface of the brick, leading to a crumbling or rough appearance. It’s essential to use the right amount of pressure when pressure washing brick to avoid such issues.

Before starting, it’s crucial to evaluate the condition of the brick. Older or softer bricks may require lower pressure to prevent damage. It’s recommended to start with the lowest pressure setting and gradually increase if necessary. Additionally, using the correct nozzle or attachment for the pressure washer can help control the pressure and prevent damage.

Another important consideration is the use of appropriate cleaning solutions. While water alone can remove dirt and grime, stubborn stains or mold may require a gentle detergent or cleaning solution specifically designed for brick surfaces. These solutions can be applied before pressure washing to enhance the cleaning process.

To prevent water damage or penetration, it’s advisable to use a downward angle when pressure washing brick. This angle helps direct the water flow away from the surface, minimizing the risk of water intrusion into the mortar or brick. It’s also essential to pay attention to the joints between the bricks as they can be more vulnerable to damage.

One effective method for cleaning exterior brick veneer involves using a spray bottle or brush to wet the bricks with water. Next, a soapy paste consisting of dish soap and table salt should be made, providing some additional grit for scrubbing. Once applied in a thin coat, the soap should be left to sit for approximately 10 minutes before a gentle scrubbing with a sponge or brush. Finally, the bricks can be rinsed with warm water to complete the cleaning process.

How Do You Clean Exterior Brick Veneer?

Cleaning exterior brick veneer requires a few simple steps to ensure a thorough and effective cleaning process. Firstly, it’s important to wet the bricks using a spray bottle or a clean brush to remove any loose dirt or debris. This initial step helps to prepare the bricks for the cleaning solution.

To create an effective cleaning solution, mix dish soap with table salt to form a soapy paste with some grit. The table salt acts as a gentle abrasive, helping to remove stubborn stains and grime from the brick surface.

Once the cleaning solution has been applied, it’s essential to allow the soap to sit for at least 10 minutes. This dwell time helps to break down any dirt or stains and makes the cleaning process more efficient. After the soap has sat for the recommended time, gently scrub the bricks using a sponge or brush, focusing on areas with heavy stains or dirt buildup.

It’s advisable to use a hose or a power washer set on a low setting to ensure a thorough rinse. Make sure to thoroughly rinse all areas, paying extra attention to corners and crevices where dirt can accumulate.

Once the bricks have been rinsed, take a step back and inspect the results. If any stains or dirt remain, you may need to repeat the cleaning process or consider using a stronger cleaning solution specifically formulated for brick surfaces. However, for regular maintenance and mild stains, this simple cleaning method should suffice.

Regular cleaning and maintenance will help to preserve the aesthetic appeal and longevity of the brick veneer, keeping it looking clean and beautiful for years to come.

Best Practices for Cleaning Brick Veneer in Different Climates or Weather Conditions

  • Use a mild detergent mixed with water to clean brick veneer.
  • Scrub the surface gently with a soft-bristle brush.
  • Rinse the brick veneer thoroughly with water to remove any residue.
  • Avoid using high-pressure washers as they can damage the brick veneer.
  • For cleaning in hot and dry climates, wet the brick veneer with water before applying the detergent to prevent it from drying too quickly.
  • In cold climates, avoid cleaning brick veneer when temperatures are below freezing to prevent damage from freezing water.
  • For areas with high humidity, consider applying a water repellent sealant to protect the brick veneer from moisture penetration.
  • Regularly inspect the brick veneer for any signs of mold or mildew growth and clean it promptly using a mixture of water and chlorine bleach.
  • Don’t use abrasive or acidic cleaners as they can erode the surface of the brick veneer.
  • It’s recommended to test any cleaning solution on a small, inconspicuous area of the brick veneer before applying it to the entire surface.


It’s crucial to remember that 2,000 PSI should be the absolute maximum pressure used, and only by experienced pressure washers.
