A pressure washer is a powerful cleaning tool that uses high-pressure water spray to remove dirt, grime, dust, mud and other unwanted materials from surfaces and objects such as buildings, vehicles and concrete surfaces. Here's a handy guide on how to use a pressure washer.

How to work a pressure washer

Knowing how to use a pressure washer properly can make the difference between a quick, effective cleaning and a long, frustrating day of work. Here are some tips that can help you use a pressure washer correctly.

1. Safety first

Before you start, make sure you are wearing appropriate safety gear. This includes closed-toe shoes, safety glasses and long pants. The high pressure of the water can cause debris to fly, so protection is crucial.

2. Connect the pressure washer

Firstly, connect the garden hose to the water supply and the other end to the pressure washer. If you're using a gas-powered pressure washer, ensure it has enough fuel. For electric pressure washers, plug it into a grounded outlet or extension cord.

3. Choose the right nozzle

Pressure washers usually come with a variety of nozzles, each of which provides a different spray pattern. For general cleaning, a 15 to 25-degree nozzle should suffice. Always remember to point the spray gun away from you and others when adjusting or changing the nozzle.

4. Start the pressure washer

Depending on the type of pressure washer you have, the starting process might differ. For a gas pressure washer, turn the fuel valve on, slide the choke on and pull the start cord. For an electric pressure washer, just switch it on.

5. Begin washing

When you're ready to start, aim the pressure washer's spray wand at the surface you want to clean, then squeeze the trigger. Maintain a consistent distance from the surface to avoid damaging it. Move the spray in a sweeping motion.

6. Clean up

Once you're done cleaning, turn off the pressure washer and disconnect it from the water supply. Drain any remaining water from the pressure washer to prevent it from freezing and damaging the machine.

Safety tips to keep in mind when using a pressure washer 

Operating a pressure washer can be dangerous if you’re unfamiliar with how to use it. Before starting any cleaning task with your pressure washer, it is crucial to wear the proper protective gear. This includes safety goggles or a face shield to shield your eyes from water, debris and cleaning agents. Additionally, dress in long sleeves, long pants and sturdy, non-slip footwear to safeguard against the high-pressure spray and potential exposure to chemicals.

Familiarising yourself with the user manual is essential. Each pressure washer model may have specific safety guidelines and operating instructions. Take the time to read and understand these guidelines to ensure safe and effective use of the equipment. 

Always turn off the pressure washer and relieve pressure before making adjustments, changing nozzles or disconnecting hoses. By adhering to these safety precautions and guidelines, you can minimise risks and create a secure environment for effective pressure washing. Prioritise safety to protect yourself and others during the cleaning process.

How to choose the right nozzle for your pressure washer 

Selecting the right nozzle is crucial for achieving optimal performance and safety when using a pressure washer. Nozzles determine the spray pattern and pressure of the water, influencing the effectiveness of the cleaning task. Here are the main types of nozzles and their specific uses:

0-Degree Nozzle (Red)

• Spray pattern — A concentrated, pinpoint jet.
• Specific use — Ideal for tough, stubborn stains or precise cleaning tasks. However, use it with caution, as the intense pressure can cause damage to surfaces or lead to injury.

15-Degree Nozzle (Yellow)

25-Degree Nozzle (Green)

• Spray pattern — A medium-angle fan.
• Specific use — Versatile nozzle for general cleaning tasks such as washing vehicles, patios and decks. It provides a balance between pressure and coverage.

40-Degree Nozzle (White)

65-Degree Nozzle (Black or Soap Nozzle)

• Spray pattern — Wide fan with low pressure.
• Specific use — Specifically designed for applying detergents or soaps. Use this nozzle when you want to pre-soak surfaces before applying more intense cleaning.

Techniques for how to use a pressure washer effectively 

Once you've grasped how to use a pressure washer, you'll want to refine your technique. Here are some tips to help you get the best results.

Maintain the right distance

The distance between the nozzle and the surface you're cleaning is crucial. If you're too close, you risk damaging the surface, especially if it's relatively soft or delicate, like wood or paint. 

Clean in a systematic pattern

Don't just spray water randomly. To achieve an even clean, it's best to use a systematic pattern. Most professionals recommend cleaning from top to bottom and from left to right. This helps prevent dirty water from dripping over already-clean areas. Also, try to maintain a consistent speed. Moving too quickly will leave streaks, while moving too slowly can cause damage or wear on the surface.

Use sweeping motions

When using the pressure washer, make long, sweeping motions. This helps to evenly distribute the water pressure and prevents the creation of "cleaning lines" where the water pressure has been uneven.

Play with angles

Sometimes, the angle at which you're spraying can make a big difference. If a surface isn't coming clean, try hitting it from a different angle. This can often help dislodge stubborn grime.

Take breaks

When learning how to work a pressure washer, it can be tiring work, especially if you're cleaning a large area. Don't try to do it all at once. Take breaks to rest and assess your work. This helps prevent fatigue and allows you to spot any areas you might have missed.
