Patio cleaning without a pressure washer
Is your patio or driveway covered in a slippery layer of green algae, moss or stubborn black spots? A pressure washer looks like a quick fix, but it often causes lasting damage to paving and joints. Patio cleaning with a stiff brush is the safer route.
Safe cleaning without a pressure washer
Why clean your patio without a pressure washer?
Blasting with high pressure seems effective, but it has three big drawbacks: it destroys the surface of the slab, blows the sand out of the joints and makes algae come back even faster next time.
Joints stay intact: brushing instead of blasting keeps the jointing sand in place. That prevents sinking and wobbly slabs.
No damage to the surface: high pressure makes slabs porous, so dirt clings on again faster. Brushing cleans without damage.
Splinter-free decking: on timber or composite decking, high pressure tears the fibres apart. Brushing prevents splinters and extends the life of your decking.
No harsh chemicals: the mechanical power of stiff bristles removes green algae with just water (or a mild cleaner such as Allround Cleaner).
The right tool: Hard 4-Jet Wash Brush 35 cm
Paving, block paving and other tough surfaces need extra scrubbing power. That's why we developed the Hard 4-Jet Wash Brush 35 cm — the heavy-duty counterpart to our soft version:
Stiff bristles: selected to loosen black spots on slabs and deep-rooted moss.
4-Jet technology: four powerful water jets spray water between the bristles directly onto the slab, so loosened dirt is rinsed away continuously.
HexaLock® system: swap between your wall brush and this stiff patio brush in seconds — see how HexaLock® works.
35 cm wide: a large brush surface for quickly cleaning driveways and garden paths. Fit it to a short aluminium pole for maximum ease.
How to clean patio slabs in 4 steps
Follow these steps for a thorough clean of your paving or decking.
Clear loose debris
First, sweep leaves and twigs off the patio so the bristles don't clog up with dirt straight away.
Pre-wet
Connect the telescopic pole with the stiff brush to your garden hose and wet the patio thoroughly, so green algae and moss can start to soften.
Add soap (optional)
Stubborn dirt or black spots? Use the SoapFlow soap dispenser with a mild cleaner, apply the suds and leave them for 5 minutes without letting them dry.
Scrub lane by lane
Turn on the water and scrub with slow, steady movements. The stiff bristles pull dirt and algae out of the pores of the slab, while the jets rinse everything away immediately.
