Spring’s here, which means it’s time to get your patio and decking ready for entertaining outdoors, and your car and caravan dirt-free before hitting the road. A pressure washer can make quick work of it all, but how do you avoid causing damage?
Pressure washers work by blasting surfaces with a high-pressure jet of water and are a great way of removing ingrained grime from patios, decking, cars, caravans and garden furniture. It’s important to use them correctly, though, as the jet is strong enough to damage car paintwork or delicate woodgrain in decking.
Our top tips on what not to do will help you use your pressure washer with confidence and make sure you get the cleaning results you want.

Don’t choose the wrong setting
Basic pressure washers come with just one lance and nozzle. But more expensive models can come with several that have different strengths and shapes of jet spray. These include:
- Variable-fan jet – ideal for cleaning delicate surfaces, such as cars, decking or chipped areas of patios, as they allow you to vary the force of the jet from a focused point to a gentler broad fan.
- Rotary jet – best for blasting ingrained dirt from patio slabs, but far too strong for delicate surfaces such as cars or decking.
- Angled lances – use for cleaning the underside of cars and garden furniture.
If your pressure washer only has a fixed jet, move it further away from the object you’re cleaning to reduce the force of the spray and avoid damage.
Don’t forget to use a patio-cleaning attachment
A patio-cleaning attachment has a plastic hood with a brush around the bottom edge which helps reduce the amount of dirty water flying around. Inside the hood there are a pair of jets that rotate at high speed close to the ground to blast off the dirt.
If you’re cleaning your patio, always try to use a cleaning attachment. It not only saves you time and makes the job easier, but we also found we stooped less when using one.
Some washers come with a patio-cleaning attachment included. But if it doesn’t, you can usually buy one for around £50

Don’t wear shorts and flip-flops
No matter how carefully you use your pressure washer, you’re more than likely going to get wet and dirty.
Avoid wearing open-toed shoes or flip-flops – instead invest in a good pair of wellies and some waterproof trousers to help keep your clothes clean.
Don’t directly blast water at your car
Rather than just trying to spray off the dirt from your car and risk damaging the paintwork, tackle the job in several steps.
- Make sure your car isn’t parked on gravel or you could blast the stones on to the car and damage it.
- Start by rinsing off the top layer of grime with a jet about 5-8cm wide; wider still on fragile areas, such as windows.
- Apply a detergent and allow it to work its magic for a few moments. Don’t let it dry or you could be left with marks that need to be buffed off by hand.
- Loosen the grime, preferably with a brush attachment. Do the wheel arches last as any small stones trapped in there could get into the brush fibres and scratch the paint elsewhere.
- Rinse off the dirt to finish. If you have a fixed-jet model, stand about a metre away from the car to avoid damaging the paintwork.

Don’t use it to remove weeds from patio
You’ll risk removing the mortar between the slabs.
Instead pull them out by hand – an old blunt knife is perfect for prising out the roots from tight gaps. You could also try a long-handled patio brush, which has a narrow, wire brush that’s ideal for getting into the cracks between slabs, or a patio knife
Once you’ve got rid of the weeds, watch our video on cleaning your patio with a pressure washer.
