What is a Pressure Washer?
A pressure washer, also known as a jet washer, is a high-pressure mechanical sprayer that can be used to remove dirt, grime, mold, dust, and other debris from hard surfaces. It works by using water to clean at a very high pressure to blast dirt off various surfaces. The water is delivered via a nozzle on the units lance which is connected to a high-pressure hose, and is powered either by electricity, petrol (known as gas in the USA), or diesel. Most DIY / consumer pressure washers such as the popular Karcher K series models, and others like Alto, Nilfisk, Black and Decker, JCB, Bosch and Hyundai are powered my mains electric supply.
Pressure washers are effective for a wide range of cleaning applications including car washing, van cleaning, driveway cleaning, concrete cleaning, and even patio cleaning. There are different types of pressure washers available, from small, portable electric models to larger, more powerful petrol-powered units.
Why Use a Pressure Washer?
Pressure washers offer several advantages when it comes to cleaning:
- Efficiency: They can clean large areas very quickly and effectively.
- Versatility: You can clean a variety of surfaces, including concrete, stone, wood, upvc, cars, vans, and patios.
- Environmentally Friendly: Pressure washing uses water, not chemicals, to clean (you can use in-conjunction with detergents if required), making it a typical green cleaning option.
- Cost-Effective: Rather than hiring professional cleaning services, you can rent or purchase a pressure washer and take care of the job yourself. This especially the case when buying a small Karcher or JCB jet washer.
Whether you’re trying to revive the look of your patio, clean your driveway, keep on top of a dirty van, or give your car a thorough wash and detail, a pressure washer can make it easier and faster than traditional cleaning methods.
How to Use a Pressure Washer
Before you start using a pressure washer, there are some important steps to take to ensure you’re getting the best results and working safely.
Preparation
- Select the right Pressure Washer
- For light-duty cleaning tasks (like washing cars, cleaning patios, or outdoor furniture), an electric pressure washer will suffice. (Take a look at models by Karcher, JCB, Bosch, Black and Decker, JCB, and Hyundai.)
- For heavier jobs (like cleaning vans, lorries, agricultural machinery, plant equipment), a diesel or petrol powered pressure washer with higher PSI (pounds per square inch) specification is more suited.
- Check your Water Supply is sufficient
- Ensure you have access to a steady water supply. Pressure washers need a constant source of water to function properly. Some models can also draw water from a large water butt or ibc container.
- Inspect the Pressure Washer before using it
- Check the pressure washer’s hose, its lance, the nozzle, and connections to ensure they are in good condition. A broken hose or clogged nozzle can reduce the effectiveness of the pressure washer.
- Gather Cleaning Detergents (If Needed)
- Some pressure washers have detergent tanks for adding cleaning detergents. You might want to use a specialised cleaner for really tough stains or to help clean mold for example from patios and driveways.
- Wear Protective Gear
- Protective eyewear, sturdy shoes, and gloves are recommended to avoid injury.
Guide to Using a Pressure Washer
Now that you’re prepared, here’s how to use your pressure washer step-by-step:
- Set Up the Pressure Washer
- Connect the hose to the pressure washer and ensure it is securely attached.
- Attach the lance and nozzle that is appropriate for your task (a wide spray for general cleaning or a narrow spray for tough stains). Some models have an adjustable nozzle, others are interchangeable ones.
- If you’re using a detergent, add it to the detergent tank / bottle or attach the detergent siphon tube.
- Turn On the Water supply
- Before you turn-on the pressure washer, make sure the water supply is turned on fully. This prevents damage to the units pump and other internal components.
- Turn on the Pressure Washer
- For electric models: Extend the electric supply cable out to where you are using the machine, plug it in and turn the power (electric supply) on.
- For diesel and petrol (gas in the USA) powered models: Follow the manufacturer’s instructions to start the engine. Most models require you to prime the pump before pulling the cord or using the built-in electric starter motor to start the jet washers engine.
- Test the Spray
- Before pointing the nozzle at the surface you want to clean, test the water spray on a small, inconspicuous area to ensure it’s the right pressure and size.
- Begin Cleaning
- Hold the nozzle about 1–3 feet from the surface to avoid causing damage.
- Move the nozzle back and forth in a sweeping motion, overlapping each stroke to ensure thorough coverage. On patios and stone surfaces you will instantly see how powerful a pressure washer is at cleaning.
- For tougher stains, you may need to get closer to the surface or use a more focused (tighter) spray.
- Rinse and Repeat
- After cleaning a section, rinse it off with just plain water. If necessary, go over particularly stubborn areas again. Drives, paths, and stone surfaces that have years of built up dirt may require a second going over.
- Turn Off the Pressure Washer
- Once you’re done the task in-hand, turn off the pressure washer and release any remaining pressure in the high pressure hose and lance by pulling the trigger.
4. Patio Cleaning with a Pressure Washer
One of the most popular uses for a pressure washer is that of cleaning patios (and driveways).
Over time, garden patios can accumulate dirt, moss, algae, and other debris, making them look weathered and unattractive. A pressure washer can make a huge difference, restoring the look of your patio in no time.
How to Clean Your Patio with a Pressure Washer:
- Prepare the Area
- Move any furniture, plant pots, garden ornaments, or plants from the patio to ensure you can clean every inch of the surface.
- Sweep away loose debris, such as leaves and twigs.
- Choose the Right Nozzle
- A wide-angle nozzle (usually 40 or 25 degrees) is best for patio cleaning, as it covers a larger surface area without damaging the material. For large patios consider buying or renting a patio cleaner attachment like the karcher T Racer or T5 attachment that can be fitted to their specific jet washer models.
- Use Detergent (Optional)
- If your patio has a lot of stains or mold, you might want to use a cleaner specifically designed for use on patios. Apply the detergent using the pressure washer’s detergent setting and let it sit for a few minutes.
- Start the Cleaning
- Begin at one corner of the patio and work your way across in sweeping motions. Overlap each stroke to ensure uniform cleaning.
- Rinse
- Once you’ve cleaned the surface, rinse it thoroughly with plain water to remove any remaining soap or detergent.
5. Pressure Washer Hire: When Should You Rent?
If you’re not sure if buying a pressure washer is worth the investment, or if you only need one for a short period or a one-off job, pressure washer hire is a good option. Renting a pressure washer allows you to complete a big cleaning project without the commitment of purchasing one of these machines.
Reasons to Consider Pressure Washer Hire:
- Occasional Use: If you only need a pressure washer for a one-time task like cleaning your patio or driveway, renting is more cost-effective.
- No Storage Space: If you don’t have room to store a pressure washer at home, renting makes more sense.
- Trying Before Buying: Renting allows you to test a pressure washer before deciding whether you want to buy one.
- Variety of Models: Rental services often offer a range of models, so you can pick the most suitable one for your project. Need to carry out some cleaning away from an electric source? consider a petrol or diesel powered machine instead!
When you opt for pressure washer hire, be sure to check the specifications of the machine to ensure it meets the requirements of your cleaning task. Additionally, make sure you understand how to operate the pressure washer before starting. For help on this just ask the staff at your local equipment and tool hire shop.
6. Pressure Washer Safety Tips
Using a pressure washer is relatively safe, but there are a few precautions to keep in mind:
- Keep the nozzle pointed away from people, animals, or any delicate surfaces. The high-pressure water can cause injury or damage if misdirected or if dirt is propelled by it as the cleaning process takes place.
- Wear protective gear. Always wear safety glasses and gloves to protect yourself from debris and flying water / items of dirt.
- Don’t spray directly at electrical outlets or wiring. Water and electricity do not mix, so keep a safe distance from outlets or electrical systems. If using an extension reel or cable keep this as far as possible away from the water.
- Be cautious when using detergents. Always read the label to ensure the cleaner is safe for the surface you’re cleaning and won’t cause damage. Pay attention on how long to leave detergents on surfaces before rinsing them off. This is especially the case with car cleaning detergents, snow foam products, and powerfull moss cleaners and stone cleaning detergents.
7. Tips for Maintaining Your Pressure Washer
To extend the life of your pressure washer, follow these maintenance tips:
- Regularly clean the units water filter. Check and clean the filter to prevent debris from clogging the system.
- Check the oil levels (for gas / petrol / diesel-powered models). Regularly check and replace the oil in the units engine as necessary. NB: Electric models are normally sealed, refer to the models instruction manual for specific details on this.
- Store it properly. Keep your pressure washer in a dry, cool place to prevent damage from the elements. In winter ensure it is stored where the temperature is above (water) freezing level.
- Flush the system. After each use, run clean water through the pressure washer to prevent internal clogs.
