Pressure Cleaning in Australia: The Expert Guide to Equipment and Technique

Pressure cleaning is one of the most effective ways to restore hard surfaces and improve your property's appearance. From driveways and patios to exterior walls and shopfronts, a high-pressure clean can remove years of dirt, grime, and mould in a single afternoon.

But to achieve professional-grade results, you need more than just a pressure washer; you need the right equipment, accessories, and technique. In this expert guide, we cover everything you need for pressure cleaning in Australia, including essential tools, safety gear, and insider tips to help you work faster and safer.

Pro tip: If you’re shopping for professional-grade tools, F&K Power Tools offers a wide range of reliable pressure washers, hoses, and accessories perfectly suited for Australian conditions.

The Fundamentals of Professional Pressure Washing

Pressure cleaning, often referenced in the field as power washing or high-pressure water blasting, is the industry-standard method for the rapid and thorough removal of surface contaminants. This process utilises a highly focused, accelerated stream of water to aggressively strip away stubborn foreign matter, including ingrained dirt, grease, oil, deteriorating paint chips, and organic growths such as moss and algae.

The operational efficiency of any pressure washing system is defined by two critical metrics:

  1. Pressure: Measured in PSI (Pounds per Square Inch), this quantifies the force with which the water strikes the surface.

  2. Flow: Measured in L/min (Litres per Minute), this quantifies the volume of water applied.

The synergistic combination of pressure and flow is what ultimately determines the unit's cleaning power and speed:

  • Low-Pressure Applications (Below 2,000 PSI): Reserved for tasks demanding finesse, such as delicate vehicle cleaning (cars, boats) and the gentle maintenance of fragile, painted, or composite surfaces.

  • Mid-Range Performance (2,000–3,000 PSI): This bracket offers the optimal balance for general exterior maintenance, proving highly effective for cleaning timber decking, fencing, and standard paved walkways.

  • High-Pressure Workhorses (3,000 PSI and Above): These machines are built for heavy-duty, commercial-grade cleaning. They are essential for deep cleaning driveways, concrete slabs, masonry, and demanding industrial applications.

Given the frequent Australian environmental challenges—specifically the pervasive issues of mould and mildew accumulation, efflorescence (salt buildup), and high dust loads—the professional's default equipment standard is typically a unit producing 3,000 PSI or greater. This power level ensures we can achieve a deep, lasting clean efficiently, minimising time on site and maximising results.

Essential Equipment for Pressure Cleaning

A proper setup ensures consistent results and prevents damage to surfaces. Here's what every cleaner should have in their toolkit.

1. Pressure Washer Unit

Choose between electric and petrol models.

  • Electric washers are quieter, lighter, and perfect for small home projects.

  • Petrol washers provide extra power and mobility—ideal for contractors or outdoor jobs where power access is limited.

Look for models with a sturdy pump, adjustable pressure control, and a flow rate of at least 7 L/min for solid cleaning performance.

2. Nozzles and Spray Tips

Nozzles determine your spray pattern and cleaning power.

  • 0° Red Tip: Focused jet for heavy stains (use carefully).

  • 15° Yellow Tip: Perfect for driveways and brickwork.

  • 25° Green Tip: Balanced option for decks and fences.

  • 40° White Tip: Safe for vehicles, glass, and painted surfaces.

A rotary or turbo nozzle combines pressure and rotation for faster coverage on large areas.

3. Extension Wands and Telescopic Lances

For reaching second-storey windows, walls, or gutters without climbing ladders. Adjustable wands also reduce fatigue by maintaining the right distance and angle.

4. Hoses and Fittings

Always use reinforced, high-pressure hoses with brass or stainless-steel fittings. Quick-connect couplers prevent leaks and expedite setup. Longer hoses reduce the need to constantly reposition your washer.

5. Detergent Systems

For stubborn stains or greasy surfaces, detergents make a huge difference. Most professional machines have a soap injector or foam cannon. Use biodegradable, non-corrosive detergents; they're safer for plants and pets and won't damage concrete sealers.

6. Safety Gear

Pressure washers can send debris flying at over 100 km/h. Always wear:

  • Safety goggles

  • Non-slip boots

  • Hearing protection

  • Long sleeves and gloves

Choosing the Right Pressure Washer

Before you buy or upgrade your machine, consider:

  • Surfaces you'll clean: Timber decks, concrete, and roofing require different pressure settings.

  • Frequency of use: Light users can opt for electric; professionals should consider petrol or commercial-grade options.

  • Ease of mobility: Wheels, long hoses, and lightweight designs help on large sites.

  • Attachments: Ensure compatibility with your favourite nozzles and foam systems.

Remember: the right balance of PSI and flow rate is better than raw pressure alone. Too much force can etch surfaces or strip paint.

Professional Tips for Better Pressure Cleaning Results

AC Clearview's technicians use proven methods to get the best finish on every job. Here's what works:

  1. Start from a distance – Begin about 60 cm away and move closer gradually.

  2. Work in consistent, overlapping strokes – Prevents visible lines and streaks.

  3. Clean in sections – Rinse before moving to the next area for even drying.

  4. Use lower pressure on soft surfaces – Timber, render, and sandstone need gentler treatment.

  5. Avoid cleaning in direct sunlight – Sudden drying can leave marks.
