The short answer
Sweep the patio, pre-wet it, apply an oxygen bleach or dedicated patio cleaner, let it dwell 10–15 minutes without drying out, scrub with a stiff deck brush, then rinse with a hose and a jet nozzle. This removes most grime and green algae film, and unlike a pressure washer it will not strip paver joint sand or etch concrete.
Oxygen Bleach Concrete Cleaner
The plant-safe cleaner that does the work during its dwell time instead of needing pressure.
A pressure washer is faster, but it is also the tool most likely to wreck a patio. On pavers it blows joint sand out; on older concrete it leaves permanent wand stripes. A brush and the right chemistry get you 90% of the result with none of that risk.
What You Need
- A stiff-bristle deck brush on a long handle — not a wire brush, which leaves rust flecks.
- Oxygen bleach (sodium percarbonate) or a concrete/paver cleaner concentrate.
- A garden hose with a jet or fan nozzle.
- A bucket, and a plastic joint scraper if weeds have taken hold.
The 5-Step Method
- 1Clear and sweep. Move furniture and planters, then sweep off loose grit so the cleaner reaches the surface instead of the debris.
- 2Pre-wet the whole patio. Dry concrete drinks cleaner unevenly and you end up with clean patches and dirty ones.
- 3Apply the cleaner and let it dwell 10–15 minutes. Mist it again if it starts drying — dwell time does most of the work, not scrubbing force.
- 4Scrub in overlapping passes, working in one direction. Green algae film releases easily; oil stains need a second application.
- 5Rinse from the high side to the low side so you never push dirty water over clean stone.
Stubborn Stains
| Stain | Treatment |
|---|---|
| Green algae film | Oxygen bleach, 15 min dwell, stiff brush |
| Black mildew spots | Concrete cleaner with mildewcide; see our mildew guide |
| Grill grease | Degreaser or cat litter to absorb first, then degreaser |
| Rust | Oxalic acid rust remover — bleach will not touch it |
| Leaf tannin | Oxygen bleach, two applications |
When You Do Want a Pressure Washer
Large driveways, heavily cemented paver joints and pre-sealing prep are genuinely faster under pressure. If that is your situation, use a surface cleaner attachment rather than a bare wand — it keeps the spray at a fixed height and avoids stripes. Our electric pressure washer and surface cleaner guides cover the sizing.
Frequently Asked Questions
- Can I use dish soap to clean a patio?
- It will cut light grease but does nothing to algae or tannin stains, and the residue attracts dirt. Use oxygen bleach or a purpose-made concrete cleaner instead.
- Does vinegar clean patio pavers?
- Vinegar kills surface algae but is acidic enough to etch limestone, travertine and some concrete pavers. Skip it on natural stone.
- How often should a patio be cleaned?
- Once a year for most patios, in spring. Shaded, damp patios that grow green film may need a second pass in late summer.
- Do I need to re-sand paver joints after brushing?
- Usually no — that is the advantage over pressure washing. Top up any joints that look low before you seal.
