Planning to pressure wash your home? Learn the key mistakes to avoid to prevent damage and achieve the best results.
This guide will walk you through common errors and how to avoid them, ensuring you don’t make a “pressure washing mistake to avoid.”
Key Takeaways
- Excessive pressure during pressure washing can cause significant damage to surfaces, so it’s essential to start with a lower pressure setting and test on a small area first.
- Selecting the correct nozzle for your pressure washer is crucial for efficiency and safety, as different nozzles provide varying spray patterns suitable for different surfaces.
- Ignoring safety measures while pressure washing can result in serious injuries, so protective gear and a clear working area are essential for safety.
Using Too Much Pressure
One of the common pressure washing mistakes is the overuse of pressure. Pressure washing mistakes can lead to damage or injury if not used carefully. It might seem logical to think that more pressure equals better cleaning, but this isn’t always the case. Excessive pressure can cause significant damage to a variety of surfaces, including:
- Siding
- Windows
- Cars
- Plants
For example, vinyl siding can be damaged by too high pressure, reaching up to 3300 psi. To avoid such mishaps, always start with a lower pressure setting and test it on an inconspicuous spot before moving to the main area.
High-pressure water can cause:
- Glass to break and window seals to malfunction
- Painted surfaces to chip off the paint, especially if directed at the surface for a few seconds
- Wooden surfaces and vinyl siding to strip away paint and even force moisture into tiny openings, leading to rot, mildew, algae, and mold
To mitigate these risks, follow these steps:
- Start with a wider nozzle at a low power setting.
- Gradually increase the pressure only if necessary.
- Always maintain a safe distance from the surface you are cleaning.
This approach will help you achieve a clean result without causing any damage by considering the mistakes to avoid.

Incorrect Nozzle Selection
The nozzle you pick for your pressure washer significantly impacts both efficiency and safety. The nozzle you select determines the spray pattern and pressure of the water. Using the wrong nozzle can either damage surfaces or be less effective in cleaning. For instance, a red nozzle creates a 0° spray pattern, which is suitable only for stripping paint off durable surfaces like concrete and metal.
A yellow nozzle with a 15° spray pattern is ideal for more versatile cleaning tasks, but it should not be used on vehicles or homes. Green nozzles produce a 25° spray pattern, making them suitable for both porous and hand-painted surfaces. The white nozzle is the safest option for fragile surfaces and provides a 40° spray pattern. Always start with a wider nozzle before switching to a narrow one to decrease the chance of damaging the surface with a narrow stream.
Ignoring Safety Measures
Disregarding safety protocols during pressure washing can result in grave injuries. The high pressure from pressure washers can be powerful enough to etch concrete, making protective gear essential. Wearing safety glasses or goggles can prevent eye injuries from flying debris and water spray. Additionally, rubber boots are crucial for maintaining traction on wet surfaces and protecting your feet from cold water and electric shock.
Other protective gear includes ear protection to prevent hearing loss from the loud noise generated by pressure washers and close-toed shoes and pants to protect against accidental spray. Before starting the pressure wash, clear the area of obstacles and tripping hazards to ensure a safe working environment with the proper safety equipment pressure washers.
Incorrect Washing Sequence
Adhering to the proper washing sequence can prevent redundant work and guarantee a comprehensive cleaning. Always start pressure washing from the roof and work your way down. This approach prevents dirty water from falling onto already cleaned areas, which would require you to clean them again.
The recommended sequence for cleaning is as follows:
- Begin with the roof
- Clean the walls and sidings
- Clean the patio or porch
- Finish with the windows
This top-down method ensures that you are not spreading dirt onto surfaces you have already cleaned, helps maintain an efficient workflow, and promotes proper ventilation.
Not Using Cleaning Solutions
The employment of cleaning agents such as soap and detergents can notably boost the efficiency of pressure washing. Water alone cannot make your home sparkle; you need more than that to do the job correctly. Cleaning solutions help to break up dirt, kill mold, and remove grime more effectively than water alone.
For instance, vinegar is an effective natural cleaner because it dissolves grime, grease, and mineral deposits. Citric acid in cleaners can break down rust and stains on wood and concrete surfaces. Using appropriate cleaning solutions makes cleaning more efficient and ensures a more thorough cleaning.
Power Washing Painted Surfaces
Pressure washing painted surfaces involves risk. The high pressure from a washer can lift the edges of paint finishes and allow water to get between the paint and the surface, causing it to peel. If the paint finish was improperly applied or the item wasn’t prepared correctly before painting, pressure washing can cause significant damage.
To avoid such issues, especially for pressure washer newbies, it is important to:
- Use an appropriate pressure setting, typically no more than 1200-1500 psi
- Use a wide-angle nozzle
- Maintain a safe distance of around 1-2 feet from the painted surface
- Test the pressure washer on an inconspicuous area first to ensure it does not damage the paint.
Washing Mold-Prone Surfaces
Steer clear of pressure-washing surfaces susceptible to mold, such as fabric and drywall. When pressure washed, these materials can trap moisture, leading to potential mold growth before they can dry out completely. Additionally, water can be forced deep into these materials, creating an ideal environment for mold to thrive.
Drywall is particularly susceptible to water damage from pressure washing, which can lead to structural issues and mold growth. High-pressure water can also exacerbate pre-existing mold problems by spreading mold spores to other areas. Instead, appropriate cleaning solutions like sodium hypochlorite can effectively remove mold and algae without causing further damage.
Using Hot Water
It’s advisable to use cold water for residential pressure washing. Hot water can warp and damage various home exteriors, furniture, and materials like vinyl siding and cedar shakes.
Cold water should suffice for most residential cleaning needs unless you are dealing with commercial-grade tasks. This approach helps to maintain the integrity of your home’s exterior surfaces while still achieving a thorough cleaning.
Lack of Proper Equipment Knowledge
Understanding your pressure washer’s functions and settings before operating it is vital to preventing expensive errors and damage. Before using a power washer, such as a gas-powered pressure washer, it is always important to read through the instruction manual. Familiarizing yourself with the manual can help ensure safe and proper usage. Each pressure washer requires a specific orifice size based on its PSI and GPM to function correctly.
Before starting, check hoses for kinks or leaks to ensure proper water flow whether you are taking the DIY route or hiring professionals, understanding how the equipment works can prevent time-consuming and expensive mistakes such as chipping off paint or breaking surfaces.
Storing Pressure Washer Improperly
Correct storage of your pressure washer during the colder months is necessary to prolong its lifespan and keep it in optimal working condition for subsequent cleaning tasks. Drain the reservoir entirely before storing a pressure washer for over 30 days during winter to prevent freeze/thaw cycles from causing damage.
To properly winterize your pressure washer, follow these steps:
- Use an air compressor to blow out the remaining liquid from plumbing and hose lines to prevent internal damage from freezing.
- Rinse the system with antifreeze before storage to protect components from freezing.
- Store the pressure washer in a dry, non-freezing location to minimize potential corrosion or weather damage.
Following these steps will help keep your equipment in top shape for years to come.
Hiring Unqualified Professionals
Employing inexperienced professionals for pressure washing may result in damage and additional costs. Unqualified pressure washing services can cause hefty damages to your property. To avoid such issues, homeowners should ask a set of questions and get multiple quotes before hiring a pressure washing company to ensure they choose reputable professionals who follow the proper pressure washing process.
By taking the time to research and select qualified professionals, you can ensure that your property is in safe hands and avoid unnecessary repair costs.
