High-Pressure Cleaning Your Property: How Much Pressure Do You Need?

There are plenty of high-pressure cleaners on the market, but how do you know which one you need? It all depends on what you want to do.




Not only is high-pressure cleaning a great way get your property looking clean and new again, but it will also help protect it against damage and deterioration, and it can even be healthier for you and your family. That’s why people want high-pressure clean everything.

Here’s what you need to know; you can’t clean everything at the same pressure. The harder the substance you’re high-pressure cleaning, the higher the pressure you can use. But you also need to think about the water pressure taking off any protective coatings you might want to stay on, like car paint for example.


Here’s a guide to understanding what water pressure you need for each type of high-pressure cleaning.

What is PSI?

Pounds per square inch, this a measurement of pressure that indicates how hard and fast the water is going to come out of the high-pressure cleaner. When looking at high-pressure cleaners, each model should clearly indicate what the PSI range of the unit is.

BBQ High-Pressure Cleaning

The metal plates of your BBQ are going to be able to withstand some fairly high pressure from the cleaner, but you’ll need to be careful of any plastic or glass around your BBQ that might get damaged.

Recommended pressure: 1400-2600 PSI


Bicycle High-Pressure Cleaning

Cleaning your bike with a high-pressure cleaner may do more damage than good so we recommend only using a low-pressure setting. Avoid applying pressure to any rubber seals on your tyres or brackets.

Recommended pressure: 1500 PSI or less


Car High-Pressure Cleaning

High-pressure cleaning your car can be a great way to take of the dirt for an off-road driver but using an extremely high pressure could damage the panels or take off the paint. Avoid holding the nozzle too close to your car and spread the pressure across the vehicle to avoid any potential damage.

Recommended pressure: 1200 to 1900 PSI


Decking or Wood Fence High-Pressure Cleaning

If you’re just washing the dirt off your wooden deck, you don’t need much pressure. Be careful to avoid any chips or cracks in the wood as the high-pressure cleaner could cause further damage.

Recommended pressure: 1500 PSI or less


Brick High-Pressure Cleaning

Because bricks don’t usually have a protective coating, you can use a higher pressure to clean off any dirt or mould. If you’ve got painted bricks you might want to use a lower pressure or avoid holding the nozzle too close to the bricks.

Recommended pressure: 1500 to 3000 PSI



Roof Tile High-Pressure Cleaning

Similar to bricks, you can use a high-pressure setting for terracotta roof tiles to remove moss and algae. Be mindful of gutters or antennas as the water pressure may cause damage.

Recommended pressure: 3000 to 4000 PSI



Limestone High-Pressure Cleaning

Limestone can be extremely brittle, so you need to be careful when using a high-pressure cleaner. Poured limestone or liquid limestone can usually sustain more pressure but limestone bricks can break and chip easily. Start with a low-pressure setting and increase it if you’re not seeing any damage.

Recommended pressure: 800 to 4000 PSI


Exposed Aggregate High-Pressure Cleaning


Exposed aggregate is as tough as concrete, so you can use a high pressure to clean to remove any dirt or staining. Be careful applying focused pressure around the stones in the concrete as you may loosen the material.

Recommended pressure: 3000 to 4000 PSI


Concrete High-Pressure Cleaning

As concrete is a smooth, hard material, you can use an industrial high-pressure cleaner to remove dirt and grease that can build up.

Recommended pressure: 3000 to 4000 PSI
