Understanding Pressure Washers
Types of Pressure Washers
When it comes to pressure washers, the debate between electric and petrol models is ongoing. Electric pressure washers are convenient, quieter, and perfect for light to medium-duty tasks like cleaning cars, decks, and furniture. On the other hand, petrol pressure washers offer more power and mobility, making them ideal for tackling larger, more stubborn areas like driveways and siding. Read our guide to pressure washers here.
| Type | Pros | Cons |
| Electric | Quieter, more eco-friendly, great for smaller tasks | Limited by cord length, less powerful |
| Petrol | More powerful, portable | Noisier, requires fuel, higher maintenance |
Key Components and Technical Jargon
Understanding your pressure washer’s specs is crucial. PSI (Pounds per Square Inch) measures the pressure exerted, with higher PSI models blasting away dirt more effectively. GPM (Gallons Per Minute) indicates the water flow rate, affecting how quickly you can clean a surface. BAR is another pressure measurement, commonly used outside the US, where 1 BAR equals approximately 14.5 PSI.
| Term | Definition |
| PSI | Pressure strength |
| GPM | Water flow rate |
| BAR | Metric pressure unit |
Efficient Washing Techniques
Preparation and Safety Measures
Before firing up your pressure washer, a little preparation goes a long way. Check the surface you’re cleaning for any damage or fragility, and always wear protective gear, including goggles and gloves. Ensure the area is clear of obstacles and that you’re using the correct settings and nozzles for the job at hand.
Effective Pressure Washing Methods
The key to efficient pressure washing is knowing how to adjust the pressure and choosing the right nozzle. A zero-degree nozzle produces a concentrated spray for tough stains, while a wider, forty-degree nozzle is ideal for delicate surfaces. Always start with the lowest pressure necessary to avoid damage, and work in a consistent, sweeping motion for even cleaning.
| Nozzle Color | Degree | Use |
| Red | 0° | High-intensity, precise cleaning |
| Yellow | 15° | General cleaning on hard surfaces |
| Green | 25° | Safe for most surfaces, including wood |
| White | 40° | Gentle cleaning, ideal for delicate surfaces |
Advanced Pressure Washing Tips
Choosing the Right Nozzles and Accessories
Selecting the right nozzle and accessories can significantly enhance your pressure-washing efficiency. The variable nozzle offers flexibility, allowing you to adjust the spray pattern on the fly, ideal for switching between different cleaning tasks without stopping. For tougher jobs, a turbo nozzle uses a rotating spray that combines the power of a zero-degree nozzle with the coverage of a wider spray, making it perfect for removing stubborn dirt and grime.
| Accessory | Purpose | Ideal Use |
| Variable Nozzle | Adjustable spray pattern | Versatile cleaning tasks |
| Turbo Nozzle | Rotating, high-intensity spray | Stubborn stains and dirt |
| Surface Cleaner | Wide coverage, even cleaning | Patios, driveways, decks |
| Telescopic Lance | Extended reach | High, hard-to-reach areas |
Using Detergents and Cleaning Solutions
Incorporating detergents can boost your cleaning power, especially on greasy or heavily soiled surfaces. Always choose a detergent compatible with your pressure washer and the surface you’re cleaning. For an eco-friendly option, look for biodegradable formulas that effectively clean without harming the environment. Apply detergent using a low-pressure setting or a specialised detergent nozzle to ensure thorough coverage before switching to a higher pressure for rinsing.
Maintenance and Troubleshooting
Routine Maintenance Tips
Regular maintenance keeps your pressure washer running smoothly and extends its lifespan. After each use, flush the system with clean water to prevent mineral buildup. Check hoses and connections for leaks or wear and replace them as needed. Store your pressure washer in a dry, frost-free environment to prevent damage from freezing temperatures.
Troubleshooting Common Issues
Encountering problems with your pressure washer can be frustrating, but many issues have simple solutions. Loss of pressure can often be attributed to clogged nozzles or filters, which can be cleaned or replaced. Leaks usually occur at hose connections and can be fixed by tightening or replacing the faulty part. For more complex issues, consulting the manufacturer’s manual or seeking professional repair is advisable.
