Why Our Superb Pressure Washers Make the Best Patio Cleaners

A sparkling clean patio can transform your entire garden, making it feel brighter, fresher, and ready for entertaining. However, over autumn and winter, even the most cared-for patios tend to collect moss, algae, and grime. When this happens, the best way to clean a patio and restore its natural colour and texture is with a high-quality pressure washer. These powerful machines make short work of dirt and weathering, giving you the clean patio slabs you’ve been missing without endless scrubbing or harsh chemicals.

At Garden Machinery Direct, we stock some of the best pressure washers for patio and outdoor cleaning, alongside premium attachments and detergents that help you achieve professional results. Here, we’ll explain how to clean your patio like an expert, highlight three of our favourite power washers, and show how surface cleaners and specialist solutions can take your results to the next level.

How to Clean a Patio with a Pressure Washer

The best way to clean a patio always begins with good preparation. So, remove furniture, ornaments, and plant pots to give you full access to the whole patio area. Sweep away loose dirt and debris, and if weeds are growing between your slabs, pull them out or use a dedicated patio weed remover.

Next, connect your pressure washer to your water supply—or, if you’re using a cordless model with siphon functionality, prepare your static water source. Begin at the furthest corner of the patio, working methodically back towards the entrance. Keep the lance at a steady 45-degree angle, maintaining consistent distance and motion to ensure an even clean.

For stubborn patches, you can apply a traditional patio cleaning solution beforehand, using a scrubbing brush to gently work it into the surface. After letting the detergent dwell, rinse thoroughly using your pressure washer to reveal the natural beauty of the paving beneath. It’s worth noting that modern power washers with detergent tanks often make this step unnecessary, but we’ll reveal more about that later.

Once complete, allow the area to dry before replacing your furniture or applying a sealant. Regular cleaning using this technique will keep your patio looking smart, and garden sharp, year after year.

The Benefits of Using Surface Cleaners and Specialist Cleaning Solutions

While all of these pressure washers do a great job cleaning patio slabs, pairing them with the right accessories can make a dramatic difference. Surface cleaners, such as the Husqvarna SC 400 Surface Cleaner and STIHL RA 110 Surface Cleaner, are designed to clean large flat areas quickly and evenly. Their rotating nozzles create a consistent, splash-free result, eliminating streaks and preventing dirt from spraying onto nearby walls or plants.

As these attachments cover more ground in less time and help maintain even pressure across the surface, they help reduce the risk of damage to softer stone. So, if you’re striving for a professional finish, surface cleaners really are a game-changer. Pairing one with your pressure washer is unquestionably the best way to clean garden slabs or driveways and get the best possible results.

If your pressure washer has an integral detergent tank, specialist detergents are also invaluable. The machine mixes these solutions with water, spraying the combination through the lance onto the patio. This removes the need to apply a traditional patio cleaning solution and use a scrubbing brush beforehand. An example of one of these specialist detergents is the Husqvarna Stone & Wood Cleaner, which is excellent for general patio cleaning, as well as for lifting everyday grime from bricks, paths, and timber. The STIHL Stone and Facade Cleaner is a strong patio cleaner detergent too, being formulated to dissolve tough green growth, mould, and grime. When added to the detergent tank of a powerful jet wash patio cleaner, these solutions deliver a sublime finish—leaving patios beautifully refreshed.

Thanks to its versatility, a quality pressure washer can be used for much more than cleaning patios. They’re especially effective for cleaning driveways, paths, and exterior walls, helping prevent the build-up of algae and extending the surface’s lifespan. With the right attachments and settings, pressure washers can also clean vehicles, decking, fences, greenhouses, garden furniture, and even tools.

This makes a pressure washer an essential garden machine, suitable for use the whole year round. It offers the best way to clean patio slabs in spring, wash garden furniture in summer, clear driveways in autumn, and rinse away winter grime.
