Acid washing for stains nothing else will shift.

Acid washing is a specialist treatment that uses carefully applied acid solutions to dissolve rust, efflorescence, mineral build-up and heavy oil staining from concrete, pavers, brick and other hard surfaces. These are the stains that standard pressure washing simply can't remove — the contamination has bonded into the surface and needs chemistry, not just force, to break it down. Across the Sunshine Coast and Gympie, bore water staining, rust run-off from fittings and salt efflorescence are common problems that leave surfaces looking permanently stained. What makes ZOLB's approach different is that we know exactly which treatment to use, at what strength, and on which surface — because getting it wrong can etch or discolour the very area you're trying to clean. We apply acid washing as a targeted add-on after pressure cleaning, neutralise and rinse thoroughly, and work safely with full insurance, so you get stubborn stains gone without damage to your surfaces.

• Removes rust, efflorescence and mineral staining
• Lifts heavy oil and grease that pressure washing can't
• Correct treatment and strength for each surface — no etching
• Applied as a targeted add-on, then neutralised and rinsed
