Pressure washing can effectively clean surfaces, remove built-up dirt and grime, and restore your home’s exterior. However, improper use can lead to damage, wasted resources, and even safety hazards. If you are a pressure-washing novice, here is a comprehensive guide to safe pressure washing. 

Best Practices for Effective Cleaning

Use the Right Pressure Settings

Some surfaces are sturdy, and some are delicate, so make sure you are using the right pressure settings to avoid accidental damage. Low-pressure settings work best for wood and siding, while higher pressure works well for concrete.

Wear Protective Gear

Always wear safety goggles, gloves, and sturdy, closed-toed shoes to protect yourself from debris and high-pressure water.  You may not feel the need to be careful, but you never know when a small rock will bounce up and hit you in the eye. 

Test on a Small Area First

Before pressure washing an entire surface, test a small, inconspicuous area to ensure the pressure and detergent are appropriate and won’t damage the surface you are cleaning. This is also a good time to practice and get used to the pressure washer.  

Use the Right Cleaning Solutions

Certain surfaces may require specialized cleaning solutions to effectively remove stains and mildew. Make sure the detergent you have is safe for the surface and the environment. Your power washer’s instruction manual should include a list of recommended cleaners based on different surfaces. 

Maintain a Safe Distance

Keep at least a 10-foot distance between you and the surface you are cleaning. Holding the nozzle too close can damage surfaces. If you feel you aren’t close enough to remove the grime you are targeting, you most likely need to adjust the pressure, not get closer. 

Use Proper Technique

Start with the lowest pressure setting and the widest spray angle, gradually increasing it to the ideal amount. Use consistent, up-and-down, sweeping motions to avoid uneven streaks or damage to the surface.

Follow Manufacturer Guidelines

Always refer to your pressure washer’s manual as it contains important information regarding how you pressure washer works, how to safely operate it, and what not to do. It will contain details about your specific washer as each one is a bit different. 

Hire a Professional 

If you are nervous about pressure washing, have a large area that needs cleaning, or don’t know how to start, consider hiring a professional. They will know the correct cleaners, techniques, and pressure to use to effectively clean your home or business without damaging it. 

Pressure Washing Precautions

Avoid Excessive Pressure

Using too much pressure can lead to accidental damage to your home or business. Heavy force can strip paint, damage wood, and crack siding. Make sure you always adjust pressure settings based on the material being cleaned and remember to not underestimate the strength of your power washer. 

Be Careful Around Windows or Electrical Components

Avoid directing high-pressure water at windows, electrical panels, or outlets, as it can cause damage and potential safety risks. You should be extra careful around anything electrical as a short circuit could lead to a fire. Unnecessary damage can also lead to costly repairs. 

Stay Off Ladders

The force of the pressure washer can cause instability, making ladder use dangerous. Instead, use extension wands for high areas to avoid the risk of injury or even death. 

Avoid Hot Water

Certain materials, such as wood and vinyl, can warp or become damaged when exposed to high-temperature water. Make sure you use the right temperature of water for the material you are cleaning; most can be cleaned using cold water. 

Ensure Proper Drainage

After pressure washing, ensure proper drainage and avoid leaving standing water to prevent mold, mildew, and water damage.

Avoid Aiming at People or Pets

Don’t point the jet of water at any person, animal, or part of your body. The pressure from the jet can be powerful enough to rip your skin off and injure those around you. 

Cover Plants and Outdoor Furniture

Prepare your property for pressure washing by covering nearby plants, outdoor furniture, and delicate decorations from harsh chemicals and high-pressure water.

Be Smart When Using a Pressure Washer

 Pressure washing can help you easily and effectively clean the exterior of your home or business. But if not used correctly, it could lead to costly damage and even injuries. Make sure to follow this guide to safely achieve a clean, polished look that will be the envy of the neighborhood.
