If you’ve never had a patio professionally washed, the before-and-after difference is often striking. Patio pressure washing can take a surface that looks permanently dirty and restore it to something that looks almost new. Understanding what’s realistic for your specific surface helps you prepare for the service.
What Can Be Fully Removed
Professional pressure washing completely removes general dirt and grime accumulation, algae and mildew on surface and in joints, pollen and atmospheric deposits, most organic staining from leaves and tree debris, light oil staining when combined with degreaser, and biological growth on mortar lines in brick and paver patios.
What May Require Additional Treatment
Heavy Oil Stains
Motor oil and cooking grease that have been on the surface for years may lighten but not disappear completely from a single pressure washing. Multiple treatments with hot water and commercial degreaser, or a topical stain treatment, may be required for full removal.
Rust Stains
Iron staining from metal furniture or fertilizer requires oxalic acid treatment rather than pressure alone. Applied correctly, this removes most rust staining completely — but it needs to be part of the service plan, not an afterthought.
Efflorescence
White mineral deposits on concrete and masonry (efflorescence) are caused by water carrying soluble salts to the surface. Acid-based cleaners are needed to dissolve this material. Pressure alone doesn’t address efflorescence effectively.
Setting the Right Expectations
Communicate the history of your patio’s staining to the contractor before the job. A professional team will give you an honest assessment of what’s achievable and what additional treatments may be needed. Transparency about limitations before the job is a sign of a quality contractor.
