4 Surfaces to Never Pressure Wash (and 6 That Need Special Care)

Pressure washing is a popular and effective method for cleaning many surfaces around your home or business. However, some surfaces should never be pressure washed due to potential damage, and some require professional care.


Here are the four surfaces you should never pressure wash.

4 Surfaces to Never Pressure Wash 

Windows: High-pressure water can damage window frames and seals, leading to leaks and drafts. Additionally, the high pressure can crack or break the glass, leading to costly repairs. Instead, use traditional cleaning methods like soap, water, or squeegee to clean windows.


Electrical fixtures: Pressure washing electrical fixtures like outlets and light switches can cause electrical shock or damage to the wiring. It’s best to avoid pressure washing these fixtures altogether.


AC units: Pressure washing AC units can damage delicate fins and coils, decreasing efficiency and increasing energy costs. It can also cause water to enter the unit, leading to electrical damage or short circuits. Instead, use a soft brush to clean the fins and coils.


Delicate landscaping: High-pressure water can damage the roots and foliage of delicate landscaping like flowers and plants, causing them to wilt or die. It’s best to avoid pressure washing around delicate landscaping and use other cleaning methods instead.


6 Surfaces You Can Pressure Wash With Special Care 


Stucco Home Exterior: High-pressure water can damage the delicate surface of stucco, causing it to crack or crumble. It can also strip the protective coating, leaving the stucco vulnerable to moisture and weather damage. These surfaces require meticulous care from a professional pressure-washing team.


Brick: High-pressure water can cause the mortar to dislodge if not done correctly, leading to weakened or unstable walls and walkways. It can also cause the brick to become chipped or cracked, affecting its structural integrity. To clean brick, we use a specialized washing process to get the deepest clean without damage.


Wooden decks and fences: High-pressure water has the potential to damage the wood, causing it to splinter or become warped. It can also strip away the protective outer coating, leaving the wood vulnerable to rot and decay. So instead of pressure washing in the traditional sense, we use a gentle system to keep your wooden surface looking fresh.


Roofs: High-pressure water can strip away the protective coating on roofs, leading to leaks and water damage. It can also dislodge shingles or tiles, causing them to break or become loose. Instead of pressure washing, you should contact the experts with the right tools to do the job right. 


Outdoor furniture: Understand your furniture. Metal furniture can withstand a power wash, whereas a high-pressure pressure wash can damage the fabric of outdoor furniture, causing it to fade or become discolored. It can also strip away the protective coating, leaving the furniture vulnerable to weather damage. Instead, use a gentle detergent and a soft-bristled brush to clean outdoor furniture. 


Cars: High-pressure water can damage the paint and exterior of vehicles, causing them to peel or chip. It can also force water into the engine or electrical components, leading to expensive repairs. Instead of pressure washing, use a low-pressure hose and mild detergent to clean the car.


Pressure vs. Power Washing: Which is Right for You?

It’s important to note that pressure and power washing are different. Power washing uses heated water, while pressure washing uses unheated water. As a result, power washing is often better for removing tough stains and grime, while pressure washing is better for lighter cleaning tasks. When deciding which method to use, consider the surface you are cleaning and its sensitivity to water pressure and heat.


While some surfaces should never be pressure washed, some can be power washed but not pressure washed. For example, surfaces like concrete, asphalt, and metal can withstand the high pressure of power washing but may be damaged by heat. Consult a professional power-washing company to determine which method is best for your specific cleaning needs.


Pressure vs. Power Washing


A pressure wash and a power wash are both methods of using high-pressure water to clean surfaces, but there are some critical differences between the two.


Pressure washing typically uses cold water and high pressure to remove dirt and grime from surfaces such as sidewalks, decks, and fences. The pressure is generally measured in pounds per square inch (PSI) and can range from 1,000 PSI to over 4,000 PSI, depending on the equipment being used. 


On the other hand, power washing uses hot water and high pressure to remove tougher stains such as oil, grease, and mildew. The high pressure is still measured in PSI, but power washing equipment typically has a higher PSI rating than pressure washing equipment. In addition, power washing can use heated water, which can help to dissolve stubborn stains and make cleaning more effective.


Another critical difference between the two methods is that power washing requires more powerful and expensive equipment and a higher level of skill. On the other hand, pressure washing is generally considered a more accessible and user-friendly option for most homeowners and small businesses.


Ultimately, whether to choose pressure washing or power washing will depend on the specific cleaning needs of the surface in question. For example, if you are dealing with tough stains and heavy grime, power washing may be better, while pressure washing may be sufficient for lighter cleaning tasks. It is always recommended to consult with a professional to determine the best approach for your specific cleaning needs.
