A standard pressure cleaning workflow helps restore grimy driveways, mildewed siding, and stained patios quickly while protecting surfaces, plants, and surrounding areas. It starts with a full inspection for cracks, loose materials, electrical risks, and drainage, then site preparation like clearing debris, shielding plants and outlets, confirming the water source, and setting up safety measures. Next, you check equipment and PPE, test a small patch to confirm settings, remove dry debris, and pre-wet surfaces where appropriate. After that, apply a pre-treatment and allow proper dwell time, lightly agitate stubborn spots if needed, then complete the primary wash using consistent distance, angle, and overlapping passes (typically top-down). Finally, rinse thoroughly and confirm all residue is removed, ensuring a clean finish without etching, streaking, or runoff issues.
Step-by-Step Standard Pressure Cleaning
Step-by-Step Standard Pressure Cleaning is a structured, repeatable method for cleaning surfaces with a pressure washer by following a safe, logical sequence, from inspection and site setup to testing, applying detergent or pre-treatment, controlled washing, thorough rinsing, and final cleanup.
The goal is to achieve consistent results while preventing common problems like etched concrete, stripped paint, forced water intrusion, plant damage, and personal injury.
Step 1: Inspect and Scan Risks
Start strong by spotting issues before water flies. Walk the site and examine every surface. Look for cracks in concrete or siding—these can widen under pressure. Check paint for peeling; loose flakes fly off and stick elsewhere. Probe joints for wobble; unstable spots lead to uneven cleaning.
Scan for electrical risks too. Note outlets, lights, or wires near work zones. Water and power mix badly—high-pressure streams cause shocks or shorts. Assess slopes and drainage; steep areas send runoff fast, potentially flooding neighbors or eroding soil.
Why bother? This scan prevents injuries and damage. The CDC warns that pressure washer wounds look minor but can infect deeply, risking amputation if untreated. Document findings with photos. It builds trust and flags if pros need to step in.
Spend 10-15 minutes here. Jot notes on a notepad: “Crack at driveway edge—lower PSI.” This sets up success.

Step 2: Prepare the Site
Clear the deck—literally. Move furniture, toys, and pots away. Sweep leaves or dirt to cut water use later. Protect plants with tarps or wet them down first; chemicals harm greenery. Cover electrical outlets with waterproof tape. Hang “Wet Floor” signs to warn passersby.
Secure a water source. Test your hose or hookup for steady flow—no drips mid-job. Block storm drains with berms or plugs if runoff carries soap; direct flow to grass or a collection spot.
Site prep takes 20 minutes but saves hours. It keeps contaminants contained. Pros follow BMPs to capture wastewater, filtering solids before disposal to sewers or tanks. This cuts pollution—runoff with oils or detergents kills fish and clogs waterways.
Pro tip: Work from the farthest point back to your water source. It avoids tracking mud over clean spots.
Step 3: Check Equipment
Gear up right, or regret it. Inspect hoses for kinks or leaks—frayed ones burst under pressure. Tighten fittings; loose ones whip dangerously. Pick nozzles based on surface: wide fans (25-40 degrees) for broad areas, narrow (0-15 degrees) for stains.
Dial pressure to 1,500-3,000 PSI for most jobs—lower for wood, higher for concrete. Match flow to 2-4 GPM for efficiency. Don PPE: goggles, gloves, boots, long sleeves, and ear plugs. High jets lacerate skin like knives.
Safe Work Australia stresses pre-use checks to dodge failures. Test run the unit away from surfaces. Fuel gas models outside; vent electric ones from puddles.
This step? 5-10 minutes. It ensures smooth sailing.

Step 4: Test a Patch
Don’t guess—test. Pick a hidden spot, like behind a bush. Spray at planned settings. Watch for etching (fuzzy texture on stone) or stripping (paint loss). Adjust PSI down if damage shows; widen angle if streaks form.
Hold the wand 12-18 inches away, sweeping slowly. Time it: 10 seconds per square foot max. Rinse and dry; inspect after 5 minutes.
Testing spots disasters. It tunes your setup for the job. Many skip this and regret—overpressure ruins decks in seconds.

Step 5: Remove Dry Debris
Blow or sweep first. Use a leaf blower or broom to clear sand, leaves, or twigs. Why? Loose junk clogs nozzles and spreads under jets, turning cleanups messy.
This dry pass cuts water volume by 30%. It preps surfaces for even wetting. Skip it on dusty sites—stir up clouds of cake gear.
Quick and dirty: 10 minutes. Your surfaces thank you.
Step 6: Pre-Wet or Controlled Wetting
Soak lightly if grime sticks hard. Use a gentle fan nozzle to mist surfaces. It loosens dirt without pooling. Avoid unsealed wood or limestone—excess water stains.
When to skip? Dry climates or quick jobs. Pre-wetting shines on oily driveways, pulling contaminants free.
Keep it controlled: 5-10 minutes. It primes for better results.
Step 7: Apply Pre-Treatment
Spray your solution now. Choose mild, eco-friendly mixes for mildew or grease. Coat evenly with a low-pressure pump sprayer. Let it dwell 5-15 minutes—longer breaks bonds, but watch for drying.
Dwell time matters: It softens stains without harsh scrubs. Never mix recipes yourself; pros calibrate for safety.
Apply from bottom up to avoid drips. This step transforms tough jobs.
For more on chemicals and pre-treatment overview, see our guide.
Step 8: Agitate When Needed
Stubborn spots call for action. Use soft brushes or agitation tools to loosen buildup. Go gentle on siding—circular motions prevent gouges. Aggressive for concrete grease, but feather edges.
Agitation boosts efficiency 20%. It targets without full blasts. Skip on fragile glass or fresh paint.
5 minutes per zone. Precision pays off.
Step 9: Primary Wash Pass
Time to blast. Start top-down on verticals like walls—gravity aids flow. Overlap strokes 50% for no gaps. Hold 12-24 inches away, 45-degree angle. Pace steady: 1 foot per second.
Sweep side-to-side on flats. Adjust for contours. This even pass removes 80% of grime.
Watch distance—too close etches; too far leaves residue. For nozzle tips, check our nozzles and pressure matching page.
Step 10: Rinse and Neutral Check
Flush top-down again. Use fresh water to wash away suds. Test pH strips on runoff—neutral (6-8) means no residue lingers.
Rinse verifies cleanliness. Acidic traces corrode; alkaline soaps haze glass. Double-rinse plants.
10-15 minutes. Clear water signals done.
Step 11: Detail Pass
Zoom in on edges, corners, and joints. Switch to pinpoint nozzles. Probe crevices gently—high pressure here blasts seals.
Details make pros shine. They catch 10% of missed spots. Use extensions for heights.
5-10 minutes. Perfection lives here.
Step 12: Post-Clean Protection Suggestions
Seal the deal—literally. Suggest clear sealers for concrete or wood. They repel stains for 1-2 years. Apply after full dry (24 hours).
High-level: Sealers lock in cleanliness. Discuss options lightly; match to surface.
Optional, but smart. It extends your work.

Step 13: Cleanup and Pack-Down
Depressurize safely: Trigger wand till dry. Rinse gear with fresh water. Coil hoses loosely.
Handle waste: Collect runoff in buckets or vacuums. Filter solids; dispose per local rules. BMPs guide this—pump to sanitary sewers, not storms.
Pack tidy. It wraps jobs pro.
Step 14: Post-Job Inspection and Client Handover
Walk with the client. Point out shines and tips. Share before/after photos. Note maintenance: Clean quarterly in humid spots.
Hand over a report: Issues fixed, next clean date. It builds loyalty.
Final touch: Thank them. Jobs end strong.

Surface Sensitivity Quick Guide for Standard Pressure Cleaning
Not all surfaces handle pressure the same. Why vulnerable? Soft or porous ones absorb force, leading to cracks or fuzzing. Here’s why and how:
- Concrete/Brick: Tough, but unsealed etches. Why? Abrasive jet pits texture. Use 2,500 PSI max.
- Wood Decks: Splinters easy. Why? Fibers tear under blast. Low 1,200 PSI, wide fan.
- Vinyl Siding: Warps hot. Why? Heat flexes plastic. Cool water, 1,500 PSI.
- Stucco: Cracks fragile. Why? Brittle coat chips. Soft wash, no direct hit.
- Glass/Windows: Shatters edges. Why? Seals blow out. Avoid direct; rinse only.
Match settings or risk repairs. Test always.

FAQs
1. What is the correct order to pressure clean?
Ans. Follow inspection first, then prep, equipment check, test patch, debris removal, pre-wet, pre-treat, agitation, main wash, rinse, details, protection, cleanup, and handover. This order prevents damage and ensures even results. Skipping steps leads to streaks or hazards.
2. Do I pre-treat before pressure washing?
Ans. Yes, for tough grime like mildew or oil. Apply a mild solution and let it sit 5-15 minutes to loosen bonds. It cuts pressure needs, protecting surfaces. Skip on light dirt to save time.
3. How do I avoid streaks/striping?
Ans. Overlap strokes 50% and keep steady distance (12-18 inches). Use consistent speed—too slow digs lines. Start with wider nozzles and test patches. Even pressure flow prevents this common woe.
4. How do I prevent etching concrete?
Ans. Lower PSI to 2,000-2,500 and use 25-degree nozzles. Hold the wand 18+ inches away at 45 degrees. Test first—etching fuzz texture from over-blast. Seal post-clean for protection.
5. How close should I hold the nozzle?
Ans. 12-24 inches for most surfaces; closer (6-12) for stains, but never touch. Too near gouges; too far weakens clean. Angle at 45 degrees for control. Adjust per test.
6. What should I cover or protect first?
Ans. Plants, outlets, vents, and windows top the list. Tarp greenery, tape electrics, sheet glass. Clear furniture too. Prep early—it stops water damage and slips.
7. What should I do with dirty runoff?
Ans. Collect in berms or vacuums, filter solids, and dump to sanitary sewers (check local rules). Avoid storms—they pollute waterways. BMPs like oil separators help for greasy jobs.
8. How long should I rinse?
Ans. Until water runs clear—5-10 minutes per section. Double-pass top-down. Test pH for neutral; residues corrode. Thorough rinse locks in shine.
9. What is a test patch and why does it matter?
Ans. Spray a small, hidden area at job settings. It reveals damage risks like etching. Matters because one wrong blast ruins whole surfaces. Adjust and save regrets.
10. What do I do after pressure cleaning?
Ans. Inspect for spots, suggest sealers, collect waste, and rinse gear. Share photos and tips with clients. Dry fully (24 hours) before foot traffic. Maintain quarterly.
