Pressure Washing Your Melbourne Driveway: Rules and Best Results

A clean driveway can add thousands to your property's kerb appeal before a sale, and in Melbourne's competitive real estate market, first impressions matter. But before you wheel out the pressure washer, it's important to understand Victoria's Permanent Water Saving Rules, which restrict how hard surfaces can be washed year-round, regardless of whether a water restriction is in force.

Victoria's Permanent Water Saving Rules: What You Can and Can't Do

Under the Permanent Water Saving Rules that apply across metropolitan Melbourne (and most of regional Victoria), washing hard surfaces such as driveways, paths, and patios with a standard garden hose is not permitted at any time. This is a permanent rule, not a seasonal restriction.

• What is not allowed: Using a standard hose to wash driveways, paths, or other hard surfaces
• What is allowed: Using a high-pressure cleaning device rated at 9 litres per minute or less to clean hard surfaces, this is the device-specific exemption that makes professional pressure washing permissible
• Safety exemption: Water can be used to remove a safety hazard such as an oil spill or chemical contamination, regardless of method, but only to the extent necessary to remove the hazard
• Seasonal cleaning: A general clean of hard surfaces using an approved device is permitted, with Melbourne Water's guidance suggesting no more than once per season for non-hazard cleaning

Why Pre-Treatment Makes the Difference

Simply blasting a driveway with high-pressure water removes loose surface dirt but leaves behind the embedded stains that make concrete look aged: tyre rubber transfer, motor oil, iron oxide (rust from metal furniture or vehicle components), and the organic growth, moss, lichen, and algae, that Melbourne's winters encourage.

• Biodegradable degreaser pre-treatment is applied and allowed to dwell for 10–20 minutes before pressure washing, lifting oil and grease from the concrete pores
• Algae and moss growth requires a biocide treatment, pressure alone will remove visible growth but leave spores that regrow within weeks
• Tyre rubber transfer responds to a targeted rubber remover solvent applied before washing
• Rust staining requires an oxalic acid-based treatment, pressure washing will not remove it

When to Schedule Your Driveway Wash

The best time to pressure wash a Melbourne driveway is in late summer or early autumn, after the summer heat has baked in organic matter and before the winter rains arrive. Washing in winter is less effective because concrete stays damp longer, allowing algae to re-establish quickly. If you are preparing for a property sale or rental inspection, allow at least three to five days after washing before the visit so the surface fully dries and the result is visible.

• Avoid pressure washing on days over 35°C, detergents dry too quickly and leave residue before they can be rinsed effectively
• Consider a driveway sealer application after cleaning to slow future stain penetration
• Pair with a gutter clean, a driveway freshly washed but surrounded by debris-filled gutters undermines the overall impression
